Phase Comparator Circuit: Phase Comparator Circuit technique is the most widely used for all practical directional, distance, differential and carrier relays. If the two input signals are S1 and S2…
Op Amp Comparator Circuit: Op Amp Comparator Circuit - In the opamp applications discussed so far, the amplifiers use negative feedback. Under normal conditions, when negative feedback is used in…
Switching Circuits (Multivibrators) Interview Questions and Answers: 1. What is an electric switch? Ans. An electric switch is a device that can turn on or off current in an electrical circuit.…
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…
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…
What is Comparator in Electronics? - Classification and Applications A circuit used to mark the instant when an arbitrary waveform attains some particular reference level is called a comparator. The…
Comparators in Power System Articles: Static Amplitude Comparator: If the two input signals are S1 and S2 the amplitude comparator gives positive (yes) output only if S2/S1 ≤ K (Fig.…
Coincidence Type Phase Comparator: The basic concept of phase comparison is simpler in that it is possible to deal with signals of equal strength whose coincidence (or noncoinecidence) is readily…
