A peak detecting circuit includes apparatus wherein an analog input signal is applied to a pair of sample and hold circuit elements with the output of the two sample and hold circuits connected, respectively, to the two input terminals of a voltage level comparator. The output of the comparator changes phase when a peak value occurs in the input analog signal. The output of the comparator is then applied to the input of the phase change detector which, in turn, produces an output signal whenever the comparator indicates that a peak has occurred in the analog input signal.
