Pulse Modulation: Pulse modulation may be used to transmit analog information, such as continuous speech or data. It is a system in which continuous waveforms are sampled at regular intervals.…
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…
What is Sinusoidal Pulse Width Modulation?: In Sinusoidal Pulse Width Modulation the pulse-width instead of being uniform as in the waveform of Fig. 11.55 is a sinusoidal function of its…
Nonlinear Circuits Interview Questions and Answers: 1. What is a comparator and where is it used ? Ans. A comparator is essentially an op-amp operated in open-loop configuration. The output signal…
Regulated and Switching Power Supplies Interview Questions and Answers: 1. What is a regulated power supply? Ans. A regulated power supply is an electronic circuit designed to provide constant dc voltage…
Indirect Testing of Circuit Breaker: With the increase in the breaking capacity of the HV circuit breakers, it has become uneconomical and unpracticable to increase the short-circuit capacity of testing…
