Delta Modulation(DM): Delta modulation(DM) is process of modulation in which train of fixed width pulses is transmitted. Their polarity indicates whether the demodulator output should rise or fall at each…
Frequency Domain Representation: Frequency Domain Representation - A very important representation of discrete time systems can be obtained in terms of sinusoidal or complex-exponential signals. This is possible because the…
Types of Filters in Electronics: Types of filters in electronics may be of any physical form—electrical, mechanical, pneumatic, hyÂdraulic, acoustical, etc. The most commonly used filters are of the electrical…
Magnetic Tape Recorder Working Principle: The major advantage of using a Magnetic Tape Recorder Working Principle is that once the data is recorded, it can be replayed an almost indefinite…
Output Power Meter Working Principle: The Output Power Meter Working Principle is designed to directly measure the output power in an arbitrary load. The instrument provides a set of resistive…
What is Wave Analyzer?: It can be shown mathematically that any complex waveform is made up of a fundamental and its harmonics. It is often desired to measure the amplitude…
Block Diagram of Sweep Generator: Block Diagram of Sweep Generator - It provides a sinusoidal output voltage whose frequency varies smoothly and continuously over an entire frequency band, usually at…
What is Signal Generator?: What is Signal Generator? : A signal generator is a vital component in a test setup, and in electronic troubleshooting and development, whether on a service…
