Written by: Newton C. Braga
Category: Banco de Informaciones - Almanaque

 

     Circuito utilizado en receptores para silenciar o cortar el ruido de fondo (silbido) cuando no se recibe ninguna señal. Lo mismo que el limitador de ruido.

    El siguiente circuito, utilizado en receptores de telecomunicaciones, tiene el propósito de silenciar el ruido que puede afectar la reproducción del sonido. El circuito es de una publicación de 1973 y utiliza diodos comunes conectados al último IF del receptor de comunicaciones de modulación de amplitud. El circuito tiene su salida aplicada a un amplificador. El squelch es el control de silenciamiento que actúa en el circuito.
