Abstract

PERFECCIONAMIENTOS EN UN SISTEMA DE TELEVISION EN COLOR. CONSTA DE UN FILTRO DE PEINE (20) QUE RESPONDE A SEÑALES DE CONMUTACION PARA PROVEER SALIDAS SEPARADAS DE LAS CUALES SE DERIVAN LOS COMPONENTES DE LUMINANCIA Y CROMINANCIA EN LA SEÑAL DE TELEVISION. EL CIRCUITO DE TRANSLACION (45) INCLUYE PRIMER (28) Y SEGUNDO (30) FILTROS DE PASO DE BANDA; EL PRIMERO EVITA QUE LOS COMPONENTES INDESEABLES DE ALTA FRECUENCIA LLEGUEN A LOS DESMODULADORES DE CALOR DEL RECEPTOR (48) Y TRASLADA LAS SEÑALES DEL SALIDA DE CROMINANCIA DEL FILTRO DE PEINE, CON UNA RESPUESTA DE AMPLITUD SUSTANCIALMENTE SIMETRICA Y CON RESPUESTA DE FASE LINEAL.
