Abstract

EN UNA RED DE DATOS QUE COMPRENDE MULTIPLEXORES (M/X(A), ETC.) CONTACTADOS ENTRE SI POR BARRAS DE ENLACE DE DATOS (1, 2, 3), Y QUE TIENE FUENTES DE IMPULSOS DE RELOJ (MC(1), ETC.), CADA MULTIPLEXOR ESTA PROVISTO DE UN SELECTOR DE IMPULSOS DE RELOJ, VIGILA LAS SEÑALES DE PRUEBA PARA ESTABLECER EL ESTADO DE LAS SEÑALES DE IMPULSOS DE RELOJ ENTRANTES Y SELECCIONA UNA SEÑAL DE IMPULSOS DE RELOJ EN ORDEN JERARQUICO PREDETERMINADO PARA SUMINISTRAR A SU MULTIPLEXOR ASOCIADO. ALTERNATIVAMENTE, POR EJEMPLO, EN AUSENCIA DE TODAS LAS SEÑALES DE PRUEBA, EL SELECTOR DE IMPULSOS DE RELOJ AJUSTA SU MULTIPLEXOR ASOCIADO A UN SERVOMODO PARA RECEPCION, EN QUE TOMA LAS SEÑALES DE IMPULSOS DE RELOJ ENTRANTES DESDE UNO DE LOS OTROS MULTIPLEXORES COMO SU FUENTE DE TEMPORIZACION.
