Google Unveils Mobile Vision; An Open Platform Named Android
by Mark Walsh
HOPING TO SPUR THE GROWTH of the mobile industry as it did the Internet, Google on Monday announced the launch of a new mobile software platform aimed at opening up and simplifying the creation of applications and services for the cell phone.
As part of the initiative, Google has forged a broad alliance with more than 30 mobile operators and handset manufacturers including Sprint, T-Mobile and Motorola to build new devices and technologies that run on Google's Android mobile platform. Noticeably absent from the newly formed Open Handset Alliance were major wireless players including Verizon Wireless, AT&T and Apple.
The first phones using the new open platform that promises a more Internet-like mobile experience won't come out until the second half of 2008. But Google will begin releasing software development tools for Android to programmers next week.
"Today's announcement is more ambitious than any single 'Google Phone' that the press has been speculating about over the last few weeks," said Eric Schmidt, Google's chairman and CEO. "Our vision is that the powerful platform we're unveiling will power thousands of different phone models."
Schmidt emphasized during a conference call Monday with other alliance members that Google was not announcing the launch of its own mobile device at this point. Rather, the company is providing an open mobile system for handset makers and developers to create new technologies around.
"The fundamental problem that most phones people have today is that they don't have fully powered Web browsers," explained Schmidt, noting that Google so far has to create specially tailored versions of popular applications like search and gmail for mobile devices. Android will encompass a browser that delivers an end-user experience more similar to surfing the PC-based Internet.
Beyond browsing, Google and its partners also envision the new platform powering the development of more advanced Web 2.0-styled applications in areas such as online audio and video, gaming and social networking. "The Android platform, in our view, will be the first to enable those [mobile] applications on a large scale," says Schmidt.
In a similar vein, Google recently led a coalition behind the launch of OpenSocial, an open platform for developing social networking applications. Schmidt acknowledged that OpenSocial would be a good fit with the new mobile platform.
Google and others have complained that for too long wireless operators and manufacturers have maintained their networks as walled gardens, making it difficult to establish industrywide standards and costly for developers to create applications for a variety of different phones.
Through its mobile initiative, Google aims to break down those traditional industry barriers by reducing development costs and standardizing platforms.
Now many of the wireless companies that have viewed Google as a potential threat are seeking to find a balance between competing and working with the search giant.
"We see the Android platform as an exciting opportunity to launch robust wireless Internet and Web 2.0 services for T-Mobile customers in the U.S. and Europe in 2008," said Rene Obermann, chief executive of Deutsche Telekom, parent company of T-Mobile, which has already partnered with Google in Europe.
Bill Huang--general manager of China Mobile Research Institute, the research arm of China Mobile--said during the conference call that the company would use Android to extend more choices to its 340 million customers. "An open platform is the key to delivering the best mobile applications and Internet experience," he said.
When it came to new business models emerging from the alliance, however, Google and mobile executives were more tight-lipped. Schmidt foresees ad revenue-sharing deals developing between Google and wireless companies.
"We're likely to want to enter into such agreements with handset partners because sharing ad revenues produces a better overall ecosystem," he said. "I think it's highly likely we could do it."
Deutsche Telekom's Obermann agreed on sharing ad revenue, but said the alliance would not change its basic subscriber business model. "Who pays for what will remain in place," he said. Exactly how far T-Mobile and other companies are willing to open their offerings under the new partnership remains to be seen.
Verizon Wireless and AT&T, which haven't joined the Open Handset Alliance, have previously been hesitant to add Google apps to their service menus. AT&T also powers Apple's iPhone. Apple, which also isn't on board with Google, recently said it would begin opening the iPhone platform to third-party developers.
Google watchers have speculated for months about the company's plans for expanding into the mobile industry. Rumors surfaced earlier this year that the search giant might come out with its own Google phone to take on Apple's iPhone and devices from other manufacturers such as Motorola and Samsung.
Anticipation was heightened in July when Google said it might bid in the upcoming 700Mhz spectrum auction, and pushed the Federal Communications Commission to adopt open access rules that would allow any mobile application to run on any device or network within the 700 band.
On Monday, Schmidt said that its potential participation in the wireless auction and its launch of Android were unrelated. "Android will run well on all of the existing data networks," he said.
More recently, Google had reportedly been in talks with Sprint, Verizon Wireless and Vodaphone about adding its services to their phones. Sprint had announced in August that it would provide Google Search to subscribers using a new network it's building based on Wi-Max, an emerging mobile broadband technology.

FLUXSET© magnetometer mounted on a non-magnetic theodolite with radio link
Most widely used D/I flux theodolites for absolute observations have two separate units connected to each-other with cable. This solution is inconvenient and the instrument can be effected by external electromagnetic disturbances. The problem can be avoided if the magnetometer electronics is together or is close to the sensor and the magnetometer is connected to the display unit via radio link. The final goal of our project is to develop a semi-automatic instrument and procedure to carry out absolute observations.
Simple construction and low power consumption of FLUXSET magnetometer allows to put it together with a battery into a small box and place everything on the telescope of the theodolite. This way it moves together with the sensor during the whole measurement procedure. Any possible small magnetic moment will be cancelled by this method.
The display unit and the magnetometer are connected via radio link and they can be placed to enough distance not to disturb the measurement. Measured data are transmitted to the display unit by a radio transmitter.
Display unit in addition to the large scale numbers has a LED bar display too. It indicates the operation of radio connection, the output signal level with sign when we are out of the measurement range. In order to decrease the power consumption the display has automatic luminosity control. Battery power is well enough for a whole day operation. To increase measurement accuracy the display unit is equipped with a GPS wich gives a precise time stamp to the data. They are stored in a memory by remote command. At the end of measurement process the memory content can be uploaded to the processing computer via USB connection.
Angle readings have to be entered manually to the computer but a digital encoder and radio transmission of angle data is under development.
Instrument charging needs 10 to 18 V DC or 100 to 240 V AC for convenient observatory and field use.

What's the difference between a semiconductor, microchip, and integrated circuit?
21 August 2023
These terms are frequently used interchangeably, but they are quite different on a technical level. Here, we set out to explain the key differences.
Demystifying electronics engineers speak
Not everyone involved in the electronic component supply chain is an engineer, so here we try and provide a simplified explanation for common terminology electronics engineers take for granted.
What is a semiconductor?
A semiconductor is a material with electrical properties that lie between those of conductors (like metals) and insulators (like rubber). It has a unique ability to conduct electricity under certain conditions and block it under others. This characteristic allows semiconductors to serve as the foundation for electronic devices. By manipulating the flow of electrons through a semiconductor, it becomes possible to create various electronic components, such as diodes, transistors, and integrated circuits. These components play vital roles in modern technology, enabling the development of computers, smartphones, communication systems, and countless other electronic devices. Silicon is the most widely used semiconductor material due to its abundance and excellent electrical properties, making it the backbone of the semiconductor industry. Semiconductors are the fundamental materials in both microchips and integrated circuits.
The four main categories of semiconductors are:
1. Intrinsic Semiconductors: Pure semiconductor materials, such as silicon and germanium, with an equal number of electrons and holes. They have limited conductivity at room temperature.
2. Extrinsic Semiconductors: Doped semiconductor materials, where impurities (dopants) are intentionally added to increase conductivity. N-type semiconductors have an excess of electrons, while P-type semiconductors have an excess of holes.
3. Diodes: A semiconductor device formed by joining N-type and P-type materials. They allow current to flow in one direction while blocking it in the opposite direction.
4. Transistors: Semiconductors that can amplify or switch electronic signals, essential components in electronic circuits and microprocessors. They consist of NPN or PNP configurations, controlling the flow of electrons or holes between their different layers.
What is a microchip?
A microchip, is also known as an integrated circuit (IC) or chip, is a small electronic component that contains a vast number of interconnected electronic circuits and transistors. These circuits are etched onto a tiny semiconductor material, usually made of silicon. Microchips are the building blocks of modern electronics and serve a multitude of functions, including data processing, memory storage, logic operations, and signal amplification. They enable the creation of complex electronic systems within a compact and efficient form factor. Microchips are found in virtually every electronic device, from smartphones and computers to household appliances and automotive systems. Their small size, low power consumption, and high processing capabilities have revolutionised the world of technology, facilitating the development of advanced and interconnected devices that have become an integral part of daily life.
The six main categories of microchips (integrated circuits) are:
1. Microprocessor: This is a central processing unit (CPU) of a computer or electronic device. It is responsible for executing instructions and performing calculations, making it the "brain" of the system, handling tasks like data processing and controlling various components for smooth operation. A microprocessor is an integrated circuit, but not all integrated circuits are microprocessors.
While all microprocessors are integrated circuits because they have their components interconnected on a semiconductor material, not all integrated circuits are microprocessors. Integrated circuits encompass a wide range of electronic components, including microcontrollers, memory chips, digital signal processors (DSPs), and various specialised chips used for specific tasks, whereas microprocessors are a specific subset of ICs designed for general-purpose computing tasks.
2. Microcontrollers: Integrated circuits designed to control and manage specific tasks in embedded systems, often found in household appliances, automotive systems, and industrial applications.
3. Memory Chips: This is a semiconductor device used to store and retrieve digital data in electronic devices. It comes in various types, such as RAM (Random Access Memory) and ROM (Read-Only Memory), and plays a crucial role in temporarily or permanently storing data for computer operations.
4. Digital Signal Processors (DSPs): Chips designed for processing and manipulating digital signals, such as audio, video, and communication signals. DSPs are commonly used in applications that require real-time signal processing, such as audio processing, speech recognition, and telecommunications.
5. Analog Chips: An analog chip is an electronic component that processes continuous electrical signals, unlike digital chips that handle discrete signals. It is used in various applications, such as amplifying and filtering audio signals, converting physical quantities (like temperature) into electrical signals, and providing smooth and accurate voltage regulation in power management circuits.
6. Application-Specific Integrated Circuits (ASICs): This is a custom-designed integrated circuit that is created for a specific application or task. It is tailored to perform a particular function or set of functions efficiently. E.G. A Graphics Processing Unit (GPU) is a specialised ASIC that is designed specifically for rendering and processing graphics and image data. It is a type of ASIC that is optimised for graphics-related tasks, such as rendering 3D graphics, video playback, and image processing.

If you use the ‘normal’ international gateways, calling from Cambodia to abroad is very expensive. But that needn’t be, as most mobile phone providers have much cheaper international gateways.
This only applies to calls made from a mobile phone, fixed phone lines do not have access to these cheaper gateways.
Read in this Cambodia Travel Guide ‘tip & trick’ how to make cheaper phone calls from Cambodia to overseas. Of course there are other alternatives, like Skype, but we leave these out of this tip.
The international access code for Cambodia is +855. The outgoing code is 001 followed by the relevant country code (e.g. 00144 for the United Kingdom). Calling through either of the universal gateways is very expensive, but when using one of the mobile phone company’s SIM-cards, there are other so-called gateways available. International calls via these gateways are cheaper because they are based on Voice-over-IP (VoIP) technology. E.g. for Mobitel, the gateway number is 177 (dial this instead of the normal outgoing code of 001). One operator (Smart) will route the call through their own less expensive gateways by just dialing the standard plus sign (+) before the foreign country code. An overview of the cheaper gateways to use, depending on the SIM-card you use:
Phnom Penh's area code is (0)23; the code for Siem Reap is (0)63. Domestic and international calls can be made at post offices or telecom offices in most towns. Mobile phone operators cover Phnom Penh and other major cities. The country uses GSM networks, so US phones are not compatible. Mobile phones can be rented at Pochentong International Airport on arrival. Internet phones are available in some Internet cafes and provide a cheaper alternative for international calls. Internet cafes provide a fast and inexpensive service in Phnom Penh, Siem Reap and other main towns.


What you need to know about wireless speakers, and how to choose the system that suits you best.
Selecting a new speaker system to purchase has become an increasingly complex and sometimes confusing process. There are a lot of decisions to me made when it comes to finding the right combination of features and connectivity. At Bayan, we believe it’s important that you know exactly what you are buying; we don’t like to see somebody purchase a product that has features they will never use or lacks the features they desire. Because of this, we have decided to break down some of the main differences with a special focus on wireless solutions.
When it comes to wireless speaker systems, you have three main options: Bluetooth, RF network, and WiFi. We’ve listed them in order from lowest to highest in feature complexity and the size of the price tag. Let’s dive in!
Bluetooth is a simple and user-friendly wireless solution that’s already built-in to practically every modern smartphone, tablet, laptop and desktop pc. Connecting to a Bluetooth device from your phone is painless. Simply tell your phone to search for available devices, and tap on the name of the speaker you wish to connect, then wait a few seconds for the process to complete.
It is simplest to think of a Bluetooth speaker as an extension of the built-in speaker on your phone/tablet. Once connected, whatever sound would normally play from your phone’s speaker will play from the Bluetooth speaker (whether it’s music from Spotify or a video from YouTube), or a text message notification.
Bluetooth however, isn’t without its limitations. In most cases, it is only possible to connect one to one - meaning you can only connect your phone via Bluetooth to one speaker and, while connected, nobody else can connect to the speaker. However, recently Bluetooth has started to introduce more complex ways of connecting – it is possible with the right hardware to connect multiple phones to the same speaker and assign priority to which will play music over the other, and conversely it is also possible to connect one phone to multiple speakers – either as stereo paired speakers (2 speakers one of which is left and one is right, time synchronised to each other) or by daisy-chaining the speakers together (which introduces a time lag between each speaker – they are not time synchronised to each-other). Bandwidth (how fast data is transferred) can also be an issue with Bluetooth. For example, some high quality audio files are large in size and will end up sounding degraded after being transferred from your phone to the speaker. There is, however, a way around this problem; the codec, aptX has the ability to shrink the size of these high quality files so that they can be played in better quality on your Bluetooth speaker. If looking for a Bluetooth speaker, we would highly recommend that you find one with AptX compatibility (such as our fantastic Soundbook X3!)
Note: For aptX to work, it is a requirement that both the transmitting device and receiving device support aptX. Currently most Android phones will support aptX, as will Apple Mac computers, however the iPhone and iPad do not support aptX.
Additionally, using bluetooth will generally introduce a time delay into the music – normally this is not an issue, however it can be frustrating to be watching tv and seeing the lips move and then hearing the audio in your wireless earphones half a second later. This means that typically Bluetooth is not suitable for TV or live monitoring scenarios.
Note: aptX Low Latency may be used to greatly reduce the time delay between transmission and reception of the Bluetooth audio stream – but again both ends (transmitter and receiver) need to support aptX low latency!
An RF Network (Radio Frequency Network) is in many ways, from a user experience point of view, similar to a Bluetooth system. They are both simple to set up, easy to understand, and can be relatively flexible in their use. However, in most cases, your mobile phone, tablet and laptop will not be able to directly connect to an RF network as they can with a Bluetooth connection. These speakers (and headphones) are most often used when a wireless connection is required over a long distance with very little delay from source to speaker. It is also possible to link together multiple speakers via an RF network.
A popular use for this technology is in headphones designed for listening to TV. It is important that the signal strength is excellent and that there is very little delay, especially when watching and listening to somebody talk. Our ears are naturally very sensitive to speech sounds, and if they don’t match exactly with the picture, a small delay becomes very noticeable. In this case the TV is connected to a transmitter device that sends the audio data to the headphones, rather than the TV and headphones being directly connected to one another.
Another example of a common use for RF technology is in live audio situations such as radio microphones or wireless in-ear monitoring for live performances (as seen in the picture above).
Bayan use RF technology in our outdoor Soundscene products to wirelessly link our speakers together with very little delay and enough range to fill a large space with music. You use the system by connecting to one of the speakers via either Bluetooth or a 3.5mm jack cable, then link the other speakers together. One of the speakers it set to be a transmitter and the others as receivers. The reoccurring theme here is external transmitters and receivers – they do not come built in to your standard devices. In reality, all of these technologies are variations on an RF network, the difference being they operate on different frequencies and therefor have different capabilities when it comes to data transfer. That’s a topic for a whole other article so I won’t go into any more detail than that!
This is the big one. WiFi enabled speakers are what many consider the future of home audio. While they are more complex to set up and operate, the technology is advancing quickly and getting more user friendly every year. WiFi music systems are able to do some very impressive things such as stream music directly from Spotify, and send a signal played on one speaker to other speakers in other rooms of the house with such low latency (delay) that it is as if a wire were being used to connect them. It is important when looking for WiFi enabled “Multiroom” speakers to consider a few key points.
Firstly, what services do the speakers support? Most systems will support streaming from your phone/tablet as you would with a Bluetooth connection, however many options have the ability to connect directly to the streaming service (such as Spotify or Napster) eliminating the need to run the app on your phone.
How easy is it to set up? While there is a lot of technical stuff happening in the background, a well-designed system should guide you’re through the setup process in a clear and easy to understand way.
Are they futureproof? Because of the Hi-Tech nature of multiroom speakers, it is important to consider how compatible they will be with future products you may wish to purchase. The technology relies heavily on software, so it’s a good idea to make sure it will be regularly updated so that as the service evolves, your system will too.
Will they work with other speakers? Buying a set of speakers from one company is great, but in the future when you want another pair, will you be locked into buying from that company again? Some companies will tie you into their brand by stopping other company’s products from working with theirs. If you don’t feel comfortable with that, you might want to look for speaker systems that use Qualcomm’s AllPlay® technology. AllPlay® is more of a universal system that will enable any speakers running the software to communicate with one another.
Buy Bluetooth if you want simplicity and ease of use on a smaller scale, and are not worried about a delay between transmitter and receiver. Buy RF Network if you want Bluetooth but bigger and with more flexibility. Buy WiFi if you want it all! (And you’re not afraid of putting a little bit of time into learning the system). With this knowledge, head to Google and begin your search for the perfect sound solution!
Why not have a look through our Wireless Products and systems, now that you are armed with the know how you can be sure to choose the right wireless system for you.

The computing landscape is evolving rapidly. Once confined to centralized data centers, computing now extends to the outer edges of networks, empowering devices to process and analyze data closer to its origin. This paradigm shift is what we call "edge computing", and it's set to redefine how data is handled, processed, and delivered.
What is Edge Computing?
In its simplest form, edge computing involves processing data closer to the location where it's generated, rather than relying on a central cloud-based system. This "location" can be anything from a smartphone, IoT devices, an industrial machine, or even a car.
Why the Shift to Edge Computing?
Latency Concerns: For applications where milliseconds matter, such as autonomous driving, drone navigation, or augmented reality, sending data to a distant data center for processing is not feasible. Edge computing minimizes latency by bringing computation closer to the source.
Bandwidth Efficiency: With billions of devices coming online, transmitting every bit of raw data back to centralized systems isn’t efficient. By processing data on the edge, only relevant insights or compacted data are sent back, reducing the burden on network resources.
Operational Reliability: Edge devices can operate independently even when cloud connectivity is lost, ensuring critical operations in sectors like healthcare or manufacturing aren’t disrupted.
Security and Privacy: Edge computing can help in processing sensitive data locally without sending it to the cloud, addressing concerns related to data sovereignty and privacy regulations.
Innovations Driving Edge Computing
Advanced Chipsets: Powerful, energy-efficient chipsets allow even compact devices to perform robust computation.
5G Technology: The rapid speed and reduced latency of 5G enhance edge capabilities, ensuring smooth communication between devices.
AI and Machine Learning: AI models can be deployed on edge devices, enabling real-time data analytics and decision-making.
While edge computing is promising, it also presents challenges:
Standardization: With an array of devices and platforms, developing universal standards is imperative for seamless interoperability.
Management and Maintenance: Deploying, updating, and maintaining software on millions of edge devices can be daunting.
Security Risks: The decentralized nature of edge computing may expose multiple attack vectors, necessitating robust security protocols.
The Future of Edge Computing
Looking forward, we can expect edge computing to complement, rather than replace, cloud computing. The synergy between them will pave the way for a more responsive, adaptive, and efficient computing infrastructure.
Smarter Cities: With edge computing, smart city infrastructure can process data locally, leading to efficient traffic management, waste disposal, and energy consumption.
Enhanced Healthcare: Wearables can process health metrics in real time, alerting users and medical professionals to anomalies immediately.
Revolutionized Retail: Stores can use edge computing to analyze shopping behaviors in real-time, offering personalized promotions or managing inventory more effectively.
Nvidia Orin: Powerhouse for Drones
The Nvidia Orin is a game-changer when it comes to edge computing for drones. Here are its key specifications:
Process: 7 nm
Cores: 17 billion transistors, with ARM CPU cores
Performance: Over 200 TOPS (Tera Operations Per Second)
Connectivity: Multiple high-speed interfaces and advanced I/O capabilities
Though Nvidia Orin offers immense computational power, there's still a finite limit to it. As such, developers and manufacturers have to make crucial decisions about where to allocate this computing power, especially when weighing between mapping and AI.
At Robotto the Nvidia Orin is a key component in the Robotto Brain. While some manufacturers have prioritized flight assistance and object avoidance. At Robotto we’ve created methods of including robust flight planning and object avoidance through our autonomous flight system. This then allows us to dedicate computational power to AI models, bringing direct value to our customers by alleviating headaches and strengthening your bottom line.
As we move into a more interconnected era, the demand for immediate data processing and real-time insights will only grow. Edge computing emerges as a solution that addresses the inherent challenges of latency, bandwidth, and operational reliability. It promises a future where devices collect data and make intelligent decisions. In the confluence of AI, 5G, and IoT, edge computing stands as a cornerstone, promising to reshape industries and improve user experiences across the board.


Quadrature allows a length control system to count four counts for one pulse from a bi-directional (two-channel) encoder.
A two-channel encoder is capable of reporting direction as well as movement. Typically, there is an A channel and a B channel. As the shaft of the encoder turns, pulses from both channels are being sent to the length control system. The two channels are always offset by 90 degrees, so one channel will always lead the other channel depending on direction.Continue reading “Quadrature”

Analog And Digital Signal Processing:2nd (Second) Edition [NEW] Download

The DSP design is derived from that on the THEMIS spacecraft (Cully et al. 2007) with modifications that enhance the frequency response, for example, the sample rates are significantly higher. This unit receives nine signals (six voltage signals from the SDP and ADP and three signals from the SCM). It creates the electric field signals in analog, performs analog signal conditioning, the analog to digital conversion, and digital signal processing on the scientific signals. The digital signal processing includes digital filtering, spectral processing, burst memory, solitary wave detection, and data compression inside of a field-programmable gate array (FPGA). It also creates calibration signals for the SCM.
The DSP (Fig. 4) receives nine analog signals from the ADP, SDP, and SCM sensors. It performs analog signal conditioning, A/D conversion, and digital signal processing using a FPGA (Actel Corporation RTAX2000). The DSP also creates calibration signals for the SCM.
There are two DSPs on each of the MMS spacecraft. One is active while the other is an unpowered spare. The units are identical except for the signal connections and minor grounding differences. DSP A receives the analog signals and routes them directly to DSP B. The analog inputs are high impedance on each of the DSP units, so the powered-off unit does not disturb the sensor signals. The BEB, AEB, and SCM grounds are connected through DSP A directly while both DSP A and DSP B are connected to analog ground on a common backplane. There are no significant differences in performance between the two units. More information on the redundant operation of the FIELDS suit is in Torbert et al. (2014, this issue).
The network model was fit to the ADP calibrations. In performing the fit, C sh , C in , f cbl , f 1, f 2, and τ D are varied (under limits) to obtain the best result. The red lines in Fig. 6 shows the best fit to the preamplifier response in gain (top panel) and phase (bottom panel). These fits indicate that the network model, while simplified, represents the preamplifier response well. Developing such a model is critical since it allows for digital correction to the measured electric field signal. Without such correction, for example, a bipolar electron phase-space hole may appear to be a tri-polar structure due to the distortion of the complex transfer function of the preamplifier and AEB system.
The DSP flexibility, while scientifically valuable, creates a great challenge in digital testing and calibration. Each of the science signals has a number of configurations and data rates. For example, E12 (DC-coupled) can be set to any of 16 data rates. The spectral averaging can be adjusted and the broadband filters can have adjustable output rates and/or can be set to peak, average, or both. Including all signals (and analog-generated signals), the DSP basically has 2N configurations, where N is on the order of 1000, making the DSP impossible to fully test. Since digital processing is identical on all of signals, the effort concentrated on (1) calibration of individual channels at their native rates, (2) calibration of the planned in-flight configurations, and (3) automated verification of each of the signals at all of their configurations while the other signals remain in a nominal configuration.
A signal is an electromagnetic or electrical current that carries data from one system or network to another. In electronics, a signal is often a time-varying voltage that is also an electromagnetic wave carrying information, though it can take on other forms, such as current. There are two main types of signals used in electronics: analog and digital signals. This article discusses the corresponding characteristics, uses, advantages and disadvantages, and typical applications of analog vs. digital signals.
A digital signal is a signal that represents data as a sequence of discrete values. A digital signal can only take on one value from a finite set of possible values at a given time. With digital signals, the physical quantity representing the information can be many things:
Digital signals are used in all digital electronics, including computing equipment and data transmission devices. When plotted on a voltage vs. time graph, digital signals are one of two values, and are usually between 0V and VCC (usually 1.8V, 3.3V, or 5V) (see Figure 2).
Analog circuits can be complex designs with multiple components, or they can be simple, such as two resistors that form a voltage divider. In general, analog circuits are more difficult to design than digital circuits that accomplish the same task. It would take a designer who is familiar with analog circuits to design an analog radio receiver, or an analog battery charger, since digital components have been adopted to simplify those designs.
Analog signals are commonly used in communication systems that convey voice, data, image, signal, or video information using a continuous signal. There are two basic kinds of analog transmission, which are both based on how they adapt data to combine an input signal with a carrier signal. The two techniques are amplitude modulation and frequency modulation. Amplitude modulation (AM) adjusts the amplitude of the carrier signal. Frequency modulation (FM) adjusts the frequency of the carrier signal. Analog transmission may be achieved via many methods:
Much like the human body uses eyes and ears to capture sensory information, analog circuits use these methodologies to interface with the real world, and to accurately capture and process these signals in electronics.
Unlike analog circuits, most useful digital circuits are synchronous, meaning there is a reference clock to coordinate the operation of the circuit blocks, so they operate in a predictable manner. Analog electronics operate asynchronously, meaning they process the signal as it arrives at the input.
Most digital circuits use a digital processor to manipulate the data. This can be in the form of a simple microcontroller (MCU) or a more complex digital signal processor (DSP), which can filter and manipulate large streams of data such as video.
Digital signals are commonly used in communication systems where digital transmission can transfer data over point-to-point or point-to-multipoint transmission channels, such as copper wires, optical fibers, wireless communication media, storage media, or computer buses. The transferrable data is represented as an electromagnetic signal, such as a microwave, radio wave, electrical voltage, or infrared signal.
Many systems must process both analog and digital signals. It is common in many communications systems to use an analog signal, which acts as an interface for the transmission medium to transmit and receive information. These analog signals are converted to digital signals, which filter, process, and store the information.
Figure 5 shows a common architecture in which the RF analog front-end (AFE) consists of all analog blocks to amplify, filter, and gain the analog signal. Meanwhile, the digital signal processor (DSP) section filters and processes the information. To convert signals from the analog subsystem to the digital subsystem in the receive path (RX), an analog-to-digital converter (ADC) is used. To convert signals from the digital subsystem to the analog subsystem in the transmit path (TX), a digital-to-analog converter (DAC) is used.
A digital signal processor (DSP) is a specialized microprocessor chip that performs digital signal processing operations. DSPs are fabricated on MOSFET integrated circuit chips, and are widely used in audio signal processing, telecommunications, digital image processing, high-definition television products, common consumer electronic devices such as mobile phones, and in many other significant applications.
A DSP is used to measure, filter, or compress continuous real-world analog signals. Dedicated DSPs often have higher power efficiency, making them suitable in portable devices due to their power consumption constraints. A majority of general-purpose microprocessors are also able to execute digital signal processing algorithms.
A DAC provides the reverse operation. The DAC input is a binary stream of data from the digital subsystem, and it outputs a discrete value, which is approximated as an analog signal. As the resolution of the DAC increases, the output signal more closely approximates a true smooth and continuous analog signal (see Figure 7). There is usually a post filter in the analog signal chain to further smooth out the waveform.
As with most engineering topics, there are pros and cons for both analog and digital signals. The specific application, performance requirements, transmission medium, and operating environment can determine whether analog or digital signaling (or a combination) should be used.
Although many original communication systems used analog signaling (telephones), recent technologies use digital signals because of their advantages with noise immunity, encryption, bandwidth efficiency, and the ability to use repeaters for long-distance transmission. A few digital signal applications are listed below:
The goal of a DSP is usually to measure, filter or compress continuous real-world analog signals. Most general-purpose microprocessors can also execute digital signal processing algorithms successfully, but may not be able to keep up with such processing continuously in real-time. Also, dedicated DSPs usually have better power efficiency, thus they are more suitable in portable devices such as mobile phones because of power consumption constraints. DSPs often use special memory architectures that are able to fetch multiple data or instructions at the same time.
Digital signal processing (DSP) algorithms typically require a large number of mathematical operations to be performed quickly and repeatedly on a series of data samples. Signals (perhaps from audio or video sensors) are constantly converted from analog to digital, manipulated digitally, and then converted back to analog form. Many DSP applications have constraints on latency; that is, for the system to work, the DSP operation must be completed within some fixed time, and deferred (or batch) processing is not viable. 2b1af7f3a8

In today’s digital age, businesses are constantly looking for ways to optimize their communication strategies to reach their clients while maximizing their time and resources. One effective way to achieve this goal is through the use of bulk email communication systems that can target specific groups. In this article, we will explore the benefits of using these systems and how they can help businesses save time.
Firstly, bulk email communication systems allow businesses to send a single email to a large group of recipients simultaneously. This can save businesses a significant amount of time compared to individually composing and sending out separate emails to each recipient. Additionally, these systems offer a range of customization options, including personalized greetings and relevant content, allowing businesses to tailor their communication to specific groups and individuals.
Moreover, these systems enable businesses to target specific groups based on various criteria, such as facility location, class time, teacher, and date of classes. This targeted approach can help businesses reach the right audience with the right message, which can lead to increased engagement and conversions. By sending targeted emails, businesses can avoid sending irrelevant information to clients who are not a part of the group, which can reduce the likelihood of recipients ignoring further communications or marking emails as spam.
Furthermore, bulk email communication systems offer automation capabilities, which can save businesses even more time. Automated emails can be triggered by certain actions taken in the system to ensure that the client always stays up to date. This can help businesses stay organized and ensure that their communication is timely and relevant.
Finally, bulk email communication systems can help businesses save money. By using a single platform to send emails, businesses can avoid the costs associated with using multiple platforms or hiring a dedicated team to handle email communication. This can be particularly beneficial for small businesses or startups with limited resources.
In conclusion, using bulk email communication systems that can target specific groups can save businesses time and resources while improving the effectiveness of their communication strategies. By sending targeted and personalized emails, businesses can engage with their audience, increase conversions, and ultimately achieve their business goals.

Telecommunication has come a very long way over the years. The technology, though, appears to be simplistic yet carries intriguing sophistication. Now, wireless systems are highly regarded and used as entry control systems in houses and workplaces. Read the post below to understand the historical development of wireless intercom systems.
What is a Wireless Intercom?
A best intercom system primarily operates using either the electrical wiring system of a particular building, radio frequencies, WIFI, or a digital spectrum spread. The market is filled with a whole range of wireless intercom systems. Moreover, there are never before seen systems in there, and their technology is becoming intriguing and complex by the day. Going wireless is the key of the age.
History of Wireless based Intercoms
The conception of wireless intercom system is regarded to be due to John Bardeen’s works on the transistors. It is due to his work that multi-directional communications could develop. The latest in this field could be the WiFi intercom technology.
Furthermore, in the year 1982 for the first time, an intercom system was developed which had both audio and visual capabilities. Also, these systems came to be used in not only communications but also for security. For instance, the intercoms that operate on radio frequency have started being used in as baby monitors.
Some wireless intercoms come with battery operation feature. This Business Intercom System promotes portability and thus efficiency.
Issues of costing
Wireless phone intercoms systems, on the other hand, are cost efficient to a large extent. The basic costing that would be involved to retrofit the building or the home itself would mean quite a lot of extra spending.
Intercom systems do not have networks recurring cost involved. Whatever the first cost is incurred during the installation process, it essentially remains fixed to that. However, of course, there are other costs such as electricity and maintenance. Moreover, apart from that, there are endless uses for these systems just because of their practicality and efficiency.
The first intercom systems operated using the same wiring network involved in any other form of telecommunication. It communicated through low voltage signal wires. These cables were usually installed in the walls of a building. Though retrofitting older buildings and houses was an option, but again the costing involved was quite a hindrance.
Later on, a new system would come up. It operated in a non-radio wireless format. They again used the electrical wiring system of a building. They became popular in offices and home environments in the form of wireless desk intercoms. The purpose of the intercom is not limited to two-way communication alone.
In most cases the issues of privacy remain secured in a wired intercom system. Though there can be wiretappings, insertion of bugs et cetera. These are the very generic issues. On the other hand, the issues of privacy are the major problem(s) of a wireless intercom service. The major issue here is that of encryption.
The best way probably to avoid this obstacle to a great extent would mean for one not to use publically available frequencies.
In the current wireless intercoms for homes and the general spaces as well, the frequency of communication is set at 4KHz. This indeed reduces voice clarity and quality in certain situations.
In the United States of America, an encrypted wireless intercom device was first used in the sport of American football in 1996. Subsequently its usability improved and so did its use. It was employed in the Super Bowl in 1999 for the first time. Moreover, as the technology was developed, so did the increase in its use.
History of wireless intercoms has been quite interesting. It has developed as a prominent and handy device. It is not only efficient and cost effective but also most essential for office environments. Its popularity has rather increased manifolds and is also found in the new apartment and/housing societies.
Since these systems are wireless – it yet remains the most secure and private way to communicate. The risk is mitigated by the added benefits of encryption. These systems suffer from interference in the signals. These systems show promises in medical centers and hospitals which require constant monitoring of patients.
The wireless intercom systems have immense potential in disaster management as well. Essentially, the possibilities are only limited by one’s imaginations.
