Q . Differentiate between an integrator and differentiator?

Integrators

1 Integrators are circuits in which output voltage is proportional to the integral of the input.

2 The time constant RC of the circuit should be very large as compared to the time period of the input wave. 

3. The value of R should be 10 or more times larger than Xc

4. Circuit:

5 Eg:When input is a square wave output is triangular

 

Differentiators

1. Differentiators are circuits in which  output is proportional to derivative of input.

2. The time constant RC is of the circuit should be much smaller than the time period of the input wave.

3. The value of Xc should be 10 or more tlmes larger than R
