The patent relates to an improved electronic circuit and technique for providing a trigger pulse synchronized with the maximum pulse density in a random pulse train. A frequency modulated pulse train having uniform amplitude pulses is delivered to an RC circuit which provides an output waveform having maximum amplitude at the highest input frequency or maximum pulse density. The waveform is passed through a smoothing filter and amplifier to more particularly define the waveform peak, and then to a peak detector where the point of maximum amplitude is sensed using a transistor sensing circuit. A pulse output from the transistor sensing circuit is electronically modified to produce an impulse trigger spike that corresponds to the point of maximum pulse density over a wide range of input conditions.
