Abstract

Perfeccionamientos en aparatos desordenadores y reordenadores de señales de comunicación, caracterizados porque se dota a cada aparato desordenador de una pluralidad de dispositivos acoplados en cargo, conectados en paralelo, cada uno para almacenar una señal con una duración correspondiente por lo menos a un segmento de tiempo; de medios terminales de entrada y de salida para alimentar señales y para secar señales, respectivamente, de la combinación paralela; y de medios de control dispuesto para cronometrar señales, alimentadas en la práctica al dispositivo terminal de entrada, introduciéndolas y sacándolas de cada uno de los dispositivos acoplados en carga, de una forma codificada predeterminada, de modo que la señal alimentada se desintegre temporal.
