Class D Power Amplifiers - Circuit Diagram, Operation and Applications: Historically, audio amplifiers have been configured as class A, class B or class AB and the art of design is…
Class B Power Amplifier - Operation and Efficiency derivation: In Class B Power Amplifier operation, the transistor is so biased that zero signal collector current is zero. Hence class B…
Classification of Power Amplifiers: Classification of Power Amplifiers are primarily divided into two categories viz. audio power amplifiers and radio power amplifiers. Audio power amplifiers, also called the small signal…
Step Response of an Amplifier: An alternative criterion of amplifier fidelity is the response of the amplifier to a particular input waveform. Of all possible available waveforms, the most generally…
Complementary Metal Oxide Semiconductor (CMOS): With active load switching, the current drain with a low output is approximately equal to ID(sat). This may cause a problem with battery operated equipment.…
Types of Sampling Techniques: Basically there are three types of sampling techniques : (i) Instantaneous sampling, (ii) Natural sampling and (iii) Flat-top sampling. Out of these three types of sampling…
Monochrome TV Transmitter - Block Diagram and its Workings: The term monochrome stands for black and white. Thus a monochrome TV system does not process variations of colour in a…
Digital Modulation Techniques: An information bearing signal can be transmitted from one point to another point over a communication channel by using either an analog technique or digital modulation techniques.…
