Abstract

CIRCUITO DE SINCRONIZACION DE FRECUENCIA DE UN OSCILADOR EN RECEPTORES DE TELEVISION. COMPRENDE UN DISCRIMINADOR DE FASE (4) QUE RECIBE LA SEÑAL DE SINCRONIZACION EN SU PRIMERA ENTRADA (5), SUMINISTRANDO A SU SALIDA UN CONTROL DE FRECUENCIA Y/O DE FASE PARA EL OSCILADOR (1). EN LA SEGUNDA ENTRADA (6) DEL DISCRIMINADOR, MEDIANTE UN CIRCUITO DE PUERTA, SE RECIBE UNA OSCILACION DE REFERENCIA QUE ESTA ACOPLADA DE MODO FIJO A LAS OSCILACIONES DEL OSCILADOR Y CUYA FRECUENCIA DE REPETICION ES IGUAL AL MULTIPLO DE LA FRECUENCIA DE LINEA.
