{PG,1 Simultaneous pulses occurring in two or more pulse trains are suppressed, and only discretely appearing pulses of a minimum time separation are propagated. A circuit detects coincidence, by time-extending a pulse representative of the inverse of the logical conjunction of both pulses. The time-extended, inverted pulse is used as an information signal indicative of noncoincidence to control AND gates to another input of which, the pulses, regenerated from the trailing edges of the pulses of the pulse trains, are applied.
