ABSTRACT:
A method for accomplishing peak limiting of bipolar signal voltages wherein the signal is processed as a running series of half waves, each of which is individually examined and dynamically controlled in amplitude. A serially connected multiple section delay line technique is utilized to derive control signals for operating the amplitude control function. Illustrative apparatus for carrying out the method includes a thresholded light-dependent resistive attenuator controlled in part by a polarity sensitive zero-crossing detector. Also included are a number of serially connected delay stages, the output signals of which are polarity-sensed to form the bipolar signal being processed into the desired half wave sections, and are amplitude-sensed to provide the required amplitude control information.
