Abstract
La presente invención se refiere a un aparato para dividir una frecuencia C1 de reloj en una relación A/B, en donde el cociente entre B y A es un número C entero y un D restante, y en donde se permite una desviación limitada en la longitud del impulso de la frecuencia dividida, incluyendo un impulso C1 de reloj dos medios impulsos de igual longitud,- caracterizado en que el aparato incluye un primer registro para escribir en el número C, un segundo registro para escribir en el número A/D, un tercer registro para escribir en el número D, e incluye también un divisor que a su vez incluye un primer circuito comparador al cual se proporciona el contenido del primer registro y también la cuenta del primer contador, que se ha hecho avanzar gradualmente en un paso para cada impulso de reloj de la frecuencia C1 de reloj, hasta que ha alcanzado el valor del contenido en el primer registro, enviando luego el circuito de comparación una señal que reajusta un multivibrador biestable y que ajusta también el contador hasta cero, siendo generada una señal para hacer avanzar gradualmente un segundo contador, y en que el divisor contiene un segundo circuito comparador que se proporciona con la cuenta del segundo contador y también el contenido del segundo registro, y si hay igualación, el segundo circuito comparador envía una señal que ajusta el segundo contador hasta cero y también reajusta un primer interruptor que en esta estado añade un número "uno" al contenido del primer registro, antes de efectuarse la conexión con el primer circuito comparador, y también reajusta un segundo interruptor que en este estado, conecta el tercer registo en vez del segundo registro con el segundo circuito comparador.
