Abstract

Un receptor de televisión perfeccionado que comprende un circuito desmodulador para desmodular una señal de televisión modulada sobre una portadoracuyo circuito desmodulador tiene una primera entrada para la señal que ha de ser desmoduladauna segunda entrada para una señal de referencia que está acoplada en frecuencia y en fase con la señal que ha de ser desmoduladay un circuito de salida de contrafase que está conectado a un circuito de entrada de un par de transistores acoplados por emisorcaracterizado porque acoplado al circuito de colector de aquél de los transistores del par de transistores que conduce corriente para una recepción normal de la señal de televisión durante la presentación de señales "más blancas que el blanco", hay un circuito de alisamiento de una de cuyas salidas se obtiene una señal para controlar al menos una función del grupo de funciones constituido por: supresión de la señal de sintonización automáticacorrección de sintonización automáticasupresión de señal de imagen y supresión de señal de sonido.
