Abstract

Dispositivo para la restitución de informaciones, recibida en forma numérica en forma numérica MIC en código bifásico, que se presenta en forma de una señal que tiene transiciones de fase de un primer tipo a la frecuencia de un reloj de emisión y en los intervalos entre transiciones del primer tipo, transiciones de segundo tipo representativas de la información, caracterizado por comprender un reloj local de frecuencia superior a la del reloj de emisión.
