Abstract
UN MONITOR DE TABLERO NUMERICO QUE CONTROLA LA CONDICION DE VARIOS CONMUTADORES DE UN TABLERO NUMERICO ES PUESTO EN FUNCIONAMIENTO COMO RESPUESTA A SEÑALES DE RELOJ RECIBIDAS DESDE UNA FUENTE DE RELOJ EXTERNA Y SE DESACTIVA EN AUSENCIA DE LAS SEÑALES DE RELOJ. EL MONITOR DE TABLERO NUMERICO INCLUYE UN MONITOR DE CONTROL DE LLAVE QUE DETECTA EL CIERRE DE CUALQUIER CONMUTADOR DE TABLERO NUMERICO PARA FACILITAR UNA PRIMERA SEÑAL DE SALIDA, UN DETECTOR DE RELOJ PARA DETECTAR LA AUSENCIA E SEÑALES DE RELOJ Y PROPORCIONAR UNA SEGUNDA SEÑAL DE SALIDA Y CUALQUER LOGICA DE SALIDA DE MANIPULADOR CERRADO QUE RESPONDE A LAS SEÑALES DE SALIDA PRIMERA Y SEGUNDA PARA FACILITAR UNA SEÑAL DE ACTIVACION. LA SEÑAL DE ACTIVACION HACE QUE LA FUENTE DE RELOJ EXTERNA FACILITE AL MONITOR DE TABLERO NUMERICO LAS SEÑALES DE RELOJ PARA ACTIVAR EL MONITOR DE TABLERO NUMERICO .
