Abstract

UN SISTEMA DE BLOQUEO DE FASE PARA FRECUENCIA/FASE, QUE PROVEE UNA SEÑAL DE MUESTRA QUE DEBE SER BLOQUEADA EN FRECUENCIA Y EN FASE A UNA SEÑAL DE APLICACION, INCLUYE UN OSCILADOR CONTROLABLE (86) ACOPLADO A UN CIRCUITO DE MUESTREO (50-53) PARA PRODUCIR MUESTRAS DE LA SEÑAL APLICADA QUE REPRESENTAN SUBSTANCIALMENTE COMPONENTES RELACIONADOS DE FASE DE CUADRATURA DE LA SEÑAL APLICADA. UN ACUMULADOR (54, 58, 60) RESPECTIVAMENTE ACUMULA LOS COMPONENTES DE FASE DE CUADRATURA A LO LARGO DE INTERVALOS PREDETERMINADOS. UN CIRCUITO DIFERENCIADOR (62, 70) SUCESIVAMENTE ESTABLECE LAS DIFERENCIAS DE UNO DE LOS COMPONENTES CON RESPECTO A LOS INTERVALOS SUCESIVOS. LAS DIFERENCIAS (74, 8894, 108) SE UTILIZAN PARA GENERAR UNA SEÑAL DE CONTROL QUE ALTERA LA SEÑAL GENERADA POR EL OSCILADOR CONTROLADO.
