Abstract

Un sistema multicanal de comunicación eléctrica que comprende un distribuidor para hacer operativos cíclica y sucesivamente los canales medios en cada canal para sumar efectivamente los impulsos concurrentes de dos trenes de impulsos siendo los impulsos en uno de los trenes de forma de onda rectangular de duración igual al período de canal y teniendo los impulsos del otro tren de impulso una variación suave en fase con respecto a los impulsos rectangulares medios para derivar una de dichas series de impulsos del distribuidor medios para aplicar la onda de adición resultante y la onda de mensaje de un canal a un generador de impulsos para producir impulsos modulados en tiempo de acuerdo con la amplitud variable de dicha onda de mensaje.A multi-channel electrical communication system comprising a distributor for successively cycling the middle channels in each channel to effectively add the concurrent pulses of two pulse trains, the pulses in one of the trains being of rectangular waveform of duration equal to the channel period and the pulses of the other pulse train having a smooth variation in phase with respect to the mean rectangular pulses for deriving one of said series of distributor pulses means for applying the resulting addition waveform and message waveform of a channel to a pulse generator for producing time modulated pulses in accordance with the varying amplitude of said message wave.
