Low-pass filter


Posted on Mar 3, 2013

This nonlinear, passive filter circuit rejects ripple (or unwanted but fairly steady-voltage) without appreciably affecting the rise time of a signal. The circuit works best when the signal level is considerably lower than the unwanted ripple, provided the ripple level is fairly constant

The circuit has characteristics similar to two peak-detecting sample-and-hold circuits in tandem with a voltage averager.
