Abstract

Instalación transmisora para la transmisión de señales por modulación codificada de impulsos, en que el transmisor está provisto de un modulador de código conectado a un generador de impulsos, cuyos impulsos de salida son transmitidos al receptor asociado, y además, aplicados a un circuito comparador que comprende un receptor local con el fin de producir una tensión de comparación que, juntamente con la señal transmitida, controla un productor de diferencia con el fin de obtener una tensión de diferencia que controla, en el modulador de código, la transmisión de los impulsos desde el generador de impulsos, caracterizado pro el hecho de que el transmisor está provisto además de un generador de una tensión de nivel alimentado por las señales a transmitir cuya tensión de salida es aplicada como tensión de control al modulador de código y en que en el receptor local, así como también en el receptor asociado, los impulsos codificados emitidos por el modulador de código son aplicados a un modulador de impulsos en el cual los contenidos de energía de los impulsos de código aplicados al mismo son modulados por medio de una componente de tensión continua filtrada, derivada de un filtro igualador alimentado con los impulsos de código transmitidos.
