Abstract
A pulse peak detector circuit for use in measuring the peak amplitude of a fast rise time, narrow pulse width pulse as in commonly encountered in an ultrasonic non-destructive testing instrument includes two amplifying means. A first amplifying means compensates small amplitude signals for the characteristics of a unidirectional current conducting means forming a part of the detector circuit while the second amplifying means provides conventional amplification of the applied signal.
