Abstract
CIRCUITO OSCILADOR CONTROLADO.COMPRENDE UNA ENTRADA POR DONDE RECIBE UNA SEN/AL DE CONTROL Y UNA SALIDA POR DONDE SE SUMINISTRA UNA SEN/AL DE RELOJ, UN CIRCUITO DE REDONDEO PARA GENERAR UNA SEN/AL QUE ES UNA MEDIDA DE UN NUMERO DE UNIDADES PREDETERMINADAS CON LAS QUE LA SEN/AL DE CONTROL PUEDE APROXIMARSE Y UNA SEN/AL DE RESTO QUE MIDE LA DIFERENCIA ENTRE LA SEN/AL DE CONTROL Y EL VALOR APROXIMADO. UN CIRCUITO DE CONTROL DE SINTONIA CAMBIA LA SINTONIA DEL CIRCUITO OSCILADOR EN ESCALONES UNIDAD COMO UNA FUNCION DE LA SEN/AL DE SALIDA DEL CIRCUITO DE REDONDEO, ACTUANDO ESTE CIRCUITO DE CONTROL DE SINTONIA COMO UN DIVISOR ARITMETICO VARIABLE.
