Abstract
SE PRESENTA UN APARATO PARA ANULAR UN INVERSOR DE RUIDO (56) DISPUESTO EN EL INTERIOR DEL IC (45) QUE INCLUYE CIRCUITERIA (61) PARA CAMBIAR LA AMPLITUD DE LA SEÑAL AGC APLICADA A UN AMPLIFICADOR AGC (66) CON ANTERIORIDAD AL INVERSOR DE RUIDO (56) PARA, DE ESTA MANERA, HACER DESCENDER EL NIVEL DE LA SEÑAL ALIMENTADA AL INVERSOR DE RUIDO. COMO RESULTADO, LA SEÑAL ALIMENTADA AL INVERSOR ES INFERIOR AL UMBRAL DEL NIVEL DE SEÑAL NECESARIO PARA EL FUNCIONAMIENTO DEL INVERSOR DE RUIDO. ESTO HACE POSIBLE EL USO DE UN DECODIFICADOR ESTANDAR MULTIPUERTO EIA CON UN IC DE PROCESAMIENTO DE SEÑAL DE TELEVISION ESTANDAR EN EL QUE EL INVERSOR DE RUIDO NO ES ACCESIBLE DE MANERA DIRECTA PARA ANULARLO.
