Abstract

Sistema de comunicación por impulsos eléctricos multicanal una disposición transmisora que comprende medios para generar varios trenes de impulsos de canal que tienen la misma frecuencia de repetición pero fases diferentes medios para modular cada uno de dichos trenes de acuerdo con una señal que ha de ser transmitida por dicho canal medios para mezclar juntos todos dichos trenes para producir un tren de impulsos combinado medios que accionan sobre dichos impulsos de tal modo que producen una modulación de dicho tren combinado de acuerdo con una señal de sincronización periódica en adición a las modulaciones de señal de sincronización periódica en adición a las modulaciones de señal respectivo y medios para transmitir el tren de impulsos bombinado modulado sobre un medio de comunicación.Multichannel electrical pulse communication system a transmitter arrangement comprising means for generating several channel pulse trains having the same repetition frequency but different phases means for modulating each of said trains according to a signal to be transmitted by said channel means for mixing together all said trains to produce a combined pulse train means driving said pulses in such a way as to produce a modulation of said combined train in accordance with a periodic sync signal in addition to the sync signal modulations periodic in addition to the respective signal modulations and means for transmitting the modulated pumped pulse train over a communication medium.
