INTEGRATOR:–
An integrator circuit integrates the input signal with respect to time (Frequency).
The circuit diagram of integrator, the feedback element is capacitor (0.047) and input element is (10k) resistor.
IMPORTANT:-
The charge on the capacitor C, when a supply voltage of V applied is Q=CV. Where V (0) is the initial voltage produced at the output.
If a square wave signal is applied to its input, the output will be triangular (Integrated) wave.
Similarly a sine wave input produces, a cosine wave output.
The integrator is commonly used in analog computers and A/D converters.
