RC integrators can be used to convert a repetitive pulse waveform to a constant dc voltage equal to the average voltage of the waveform if:
A)τ is very large compared to tW.
B)τ is equal to tW.
C)τ is very small compared to tW.
D)τ is five times tW.

Question

Quizplus · Accepted Answer

When τ (the time constant) is very large compared to tW (the pulse width), the RC integrator effectively averages the input waveform, resulting in a constant DC voltage output equal to the average voltage of the input waveform.
