Abstract

UN FILTRO FIJO (31, 32) DETERMINA UNA PORCION INFERIOR DE LA CARACTERISTICA DE AMPLITUD DE UN FILTRO (30) DE CORRECCION DE BANDA LATERAL DE SEÑALES DE CROMINANCIA. UN FILTRO VARIABLE (34) DETERMINA LA PORCION SUPERIOR DE LA CARACTERISTICA DE AMPLITUD. UNA SEÑAL DE CONTROL (CS) SINTONIZA EL FILTRO VARIABLE, PARA PROPORCIONAR UNA RESPUESTA SIMETRICA A LAS SEÑALES DE VIDEO QUE TIENEN BANDAS LATERALES DE COLOR COMPENSADO, Y SINTONIZA EL FILTRO VARIABLE PARA PROPORCIONAR UNA RESPUESTA ASIMETRICA A LAS SEÑALES DE VIDEO QUE TIENEN BANDAS LATERALES NO COMPENSADAS.
