Abstract

A unique slope-controlled crest detector and sample-and-hold circuit for determining the peak values of a fluctuating input signal and providing a control signal indicating the time of occurrence of the peak value. This circuit successfully eliminated undesirable filtering and phase delay from the data path while incorporating adequate filtering to the slope sensing circuitry to allow good operation with poor signal-to-noise ratio on the input signal.
