Abstract
A circuit for filtering positive and negative glitches (i.e., dropouts and noise spikes) in a pulse-like signal to be processed, utilizes a single timing element which introduces a uniform delay in both the leading and trailing edges of the pulse-like signal, thus eliminating pulse-width distortion of the signal. A single adjustment may be made which has the same effect on both the leading and trailing edges making a uniform adjustment of both delays easily achieved.
