Abstract

The peak of a symmetrical signal is accurately detected. The input signal and a first delayed signal derived from the input signal are both supplied to a comparator. When the input signal and first delayed signal are equal, the comparator operates a gate which supplies to an output a second delayed signal representing the input signal peak.

Peak Detection

The peak of a symmetrical signal is accurately detected. The input signal and a first delayed signal derived from the input signal are both supplied to a comparator. When the input signal and first delayed signal are equal, the comparator operates a gate which supplies to an output a second delayed signal representing the input signal peak.

Where the input signal peak occurs at time t and the first delayed signal peak occurs at t + 2 delta t, the second delayed signal peak (which is the desired output) occurs at t + delta t. It is desirable that 2 delta t < 1/2f, where f is the signal frequency.
