ABSTRACT:
A signal peak detector which can be used for echo suppressors, has a memory in which is written a value which is variable as a function of the incident signal and represents the peak sought, an attenuator of the memorized value; four comparators; three of which compare the instantaneous value of the incident signal with, respectively the memorized value, the attenuated memorized value and a fixed threshold, and the fourth of which compares the attenuated memorized value with the fixed threshold; and a control unit which modifies the memorized value as a function of the result of those comparisons.
