Abstract

APARATO DIVISOR DE FRECUENCIA PROGRAMABLE CON UNA RED DIVISORA DE FRECUENCIA CON VARIAS ETAPAS DIVISORAS DE FRECUENCIAS PROGRAMABLES CONECTADAS EN CASCADA QUE DIVIDEN POR DOS Y TRES LA FRECUENCIA DE UN IMPULSO DE RELOJ BASADA EN UN NIVEL LOGICO DE UNA SEÑAL DE ENTRADA PREFIJADA USADA PARA CAMBIAR UNA RELACION VARIABLE DE DIVISION, Y MEDIOS DE PUERTA LOGICA PARA DETERMINAR SI CADA SALIDA DE ETAPA SE LLEVA O NO A CONFIGURACION PREDETERMINADA, Y SE INTRODUCE UNA SEÑAL DE INSTRUCCION PARA TOMAR UNA DECISION RESPECTO AL INCREMENTO EN (+1) DE LA RELACION DE DIVISION, PARA GENERAR LA SALIDA DE UN NIVEL LOGICO, HACIENDO QUE. UNA ETAPA EQUIVALENTE A UNA PRIMERA ETAPA, DIVIDA POR TRES LA FRECUENCIA DEL IMPULSO DE RELOJ SI SE DETERMINA QUE ES POSITIVO EN LA DETECCION ANTE RIOR, Y LA SALIDA DE LOS MEDIOS SE SUMINISTRA A LA ETAPACORRESPONDIENTE A LA PRIMERA PARA SELECCIONAR UNA RELACION DE DIVISION DE N Y (N+1).
