Features of Variable Voltage Inverters: The inverter has an impressed dc voltage. The output voltage of the inverter is decided by the firing and duration of the thyristors. The conduction…
Types of Electrical Drives: Types of Electrical Drives has the following major parts: load, motor, power modulator, control unit and source. There are large number of loads and each load…
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…
