An embedded system is a type of computer that can perform a few specialised tasks. This design is contrary to the normal computer that is designed to perform a number of operations that are in many cases unrelated to each other. Embedded systems are present in many of the devices that are used today and [...]

It seems that ATMEL do not want to limit the AVR branch with 20MIPS AVR microcontrollers. Recently they introduced new AVR microcontroller family - XMEGA - which is still based on AVR core but has a higher performance along with low power feature. AVR microcontrollers are really optimal where high performance is needed with relatively [...]

We know that digital signals are stored as binary numbers in memory cells. Let’s see how these digital signals can be transferred in other words - how they can be encoded in to electrical signal shape. When signal has to be sent it has to be modulated.
Pulse Code Modulation (PCM)
Probably simplest and most common modulation [...]

The processing of the various signals is carried out through implements that are together called as DSP hardware. This includes the hardware that is used for transmission of signals, various devices that are used to enhance or filter the signals, analogue to digital and digital to analogue converters and other processing equipment such as computers.
Among [...]

The term circuit technology usually refers to the various techniques that used in the manufacture of electrical circuits. A large number of devices that are used today make use of printed circuit boards (PCBs). These devices provide a mechanical support for the various components present within the given device and also, the electrical connections between [...]

The term Biosignal refers to all the signals that are being generated in the human body or any other living organism or more specifically it is used to represent all those signals from living organisms that are monitored to obtain certain useful information. Primarily, the term refers to signals that are electrical in nature but, [...]

Digital signal processing is the technique used to analyse various digital signals and obtain information form the same. It is also used for transfer of information from one place to another and also involves conversion in between analogue and digital signals.
It finds its application in various areas ranging from broadcasting to medicine.
Let us have a [...]

These are devices that are used in electronic circuits to make reconfiguration of the same possible. The logical gates that are normally used perform a fixed function however, the Programmable Logic Devices (PLD) does not perform any predefined task when they are manufactured and need to be programmed before they can be used.
Before the introduction [...]

Biomedical devices are those electrical devices that are used in medicine to carry out various tests on the human body. A lot of research has been performed in this field and as a result, these devices have become indispensable as far as medicine is concerned.
Let us have a look at some of the tasks that [...]

Processing of audio signals is one of the most important and widely used applications of digital signals processing. It is being used in many fields such as communication, broadcasting of audio signals for radios, television etc. It primarily includes analysis of audio signals that fall in the human hearing frequency by mathematical. The audio signals [...]
