Abstract

Sistema de recuperación de reloj para receptor de transmisión de datos en forma de trenes de impulsos binarios emitidos a una frecuencia de reloj fija, que comprende un contador de anillo, que tiene dos de sus salidas unidas a las entradas de una primera báscula JK, que proporciona en su salida la señal de reloj recuperada, sistema caracterizado porque lleva un circuito de accionamiento del contador de anillo que bloquea al contador de anillo a falta de información, y que acciona el contador de anillo desde que llega el primer impulso de la señal de información.
