Abstract

UN CIRCUITO DIVISOR DE FRECUENCIAS COMPRENDE UN ACUMULADOR DIGITAL CAPAZ DE LLEVAR A CABO ARITMETICA SIGNADA Y MEDIOS PARA SUMAR A UN NUMERADOR PREDETERMINADO EL CONTENIDO DEL ACUMULADOR. SE DISPONEN MEDIOS PARA RESTAR UN DENOMINADOR PREDETERMINADO AL CONTENIDO DEL ACUMULADOR Y OTROS MEDIOS DETECTAN SI EL VALOR ALMACENADO EN EL ACUMULADOR HA LLEGADO A CERO O A UN VALOR NEGATIVO, Y ESTABLECER UN VALOR DE RETARDO DEFINIDO QUE DEPENDE DEL VALOR ALMACENADO. OTROS MEDIOS CONVIERTEN EL VALOR DE RETARDO DEFINIDO EN UN TIEMPO DE RETARDO INVERSAMENTE PROPORCIONAL A LA MAGNITUD DEL VALOR DEL RETARDO DEFINIDO Y AUN OTROS MEDIOS CAMBIAN EL ESTADO DE UNA SEÑAL DIGITAL DE SALIDA AL FINAL DE DICHO RETARDO. TAMBIEN SE DESCRIBE EL PROCEDIMIENTO CORRESPONDIENTE.
