Differentiator - Integrator Circuit Interview Question Answer

1	What do you mean by differentiate circuit?
	Differentiate circuit It is circuit in which the output is directly proportional to differentiation of the input waveform.
2	What should be condition to be satisfied for differentiate circuit?
	Necessary condition for differentiate circuit The capacitive reactance should be 10 or more times than the resistance at the operating frequency. The time period of the input waveform should be more than the time constant of the RC circuit.
3	What is output of the differentiate circuit for the following input? DC, Sinusoidal waveform, Square waveform, Triangular waveform.
	Input – Output DC – Zero Sinusoidal waveform – Cosine waveform Square waveform – Sharp narrow pulses Triangular waveform – Rectangular waveform
4	What do you mean by the integrating circuit?
	Integrating circuit It is circuit in which the output is directly proportional to integral of the input waveform.
5	What should be condition to be satisfied for integrating circuit?
	Necessary condition for integrating circuit The value of the resistance should be 10 or more times than the capacitive reactance at the operating frequency. The time period of the input waveform should be very small than the time constant of the RC circuit.
6	What is output of the integrating circuit for the following input? Sinusoidal waveform, Rectangular waveform, Square waveform
	Input – Output Sinusoidal – Cosine Rectangular – Triangular Square – Triangular
