Abstract
UN APARATO EN UN SISTEMA DE TRATAMIENTO DE SEÑAL DE VIDEO, QUE COMPRENDE UN FILTRO DE SEÑAL DE FRECUENCIA INTERMEDIA (16) QUE VA DISPUESTO EN EL CANAL DE SONIDO DE FRECUENCIA INTERMEDIA Y PRESENTA RESPUESTAS DE AMPLITUD DE PICO ASIMETRICAS Y LIGERAMENTE DESPLAZADAS RESPECTO DE LAS FRECUENCIAS NOMINALES DE LAS PORTADORAS DE IMAGEN Y SONIDO EN UNA CUANTIA ESTABLECIDA POR LA INCLINACION INTRODUCIDA POR EL SINTONIZADOR Y LA SECCION DE TRATAMIENTO DE SEÑAL DE FRECUENCIA INTERMEDIA, ASI COMO UN SISTEMA DE DESMODULACION DE SONIDO (22) AL QUE SE APLICA UNA SEÑAL FILTRADA DE FRECUENCIA INTERMEDIA Y QUE PRESENTA UNA CARACTERISTICA SUSTANCIALMENTE SIMETRICA CON RESPECTO A LAS FRECUENCIAS DE LAS PORTADORAS DE IMAGEN Y SONIDO. EL INVENTO ES UTIL PARA REDUCIR EL ZUMBIDO DE AUDIO Y LA DISTORSION ARMONICA EN RECEPTORES DE TELEVISION.
