ABSTRACT:
A device for detecting, among noise, each of the pulses of a pulse train, comprising essentially: a detector detecting the peak of a pulse; a first delay line; a first comparator comparing the level of the first delayed pulse with the half peak value; a second delay line for delaying the pulse train with a second delay different from the first one; a second comparator comparing the signal delivered by a second delay line with the signal delivered by the first delay line and with the half peak value, and an AND gate delivering an output signal when there is coincidence of the output signals from said two comparators.
