Abstract

Perfeccionamientos en aparatos para comunicar señales digitales, que comprenden grupos de códigos entre dos sistemas digitales, donde un primer sistema digital se sincroniza por una primera base de tiempo y un segundo sistema digital se sincroniza por una segunda base de tiempo independiente de la primera base de tiempo en frecuencia y fase, caracterizados porque cada aparato comprende un dispositivo de almacenamiento acoplado al primer sistema digital para recibir grupos de códigos derivados de los grupos de códigos del primer sistema digital a un primer ritmo o cadencia sincronizada con la primera base de tiempo, para almacenar dichos grupos de códigos; medios de acceso para recibir el contenido del dispositivo de almacenamiento a un segundo ritmo o cadencia sincronizada con la segunda base de tiempo y para controlar la fase de los grupos de códigos, para el segundo sistema digital; medios de temporización para generar una salida indicativa de la fase relativa de los grupos de códigos delsegundo sistema digital con respecto a la fase de los grupos de códigos producidos por el primer sistema digital; medios multiplicadores acoplados a los medios de almacenamiento.
