Abstract

Modulador de impulsos codificados en que las señales que deben ser transmitidas gobiernan un modulador de impulsos conectado a un generador de impulsos equidistantes y que se halla derivado por un circuito de retorno que comprende un demodulador de impulsos codificados y luego la conexión serie de una red integradora de frecuencias de señal y un formador de diferencia al cual se aplican la tensión de retorno y las señales que deben ser transmitidas caracterizado por el hecho de que dicho circuito de retorno comprende una red adicional integradora de frecuencias de impulsos ubicados entre las frecuencias se señal y la frecuencia de repetición de los impulsos equidistantes.
