Abstract

UNA RED (30) COMBINA SEÑALES DE LUMINANCIA (V) Y CROMINANCIA (C), PARA PROPORCIONAR UNA SEÑAL DE VIDEO COMPUESTA (S4), EN LA QUE LA SEÑAL DE CROMINANCIA SE SOMETE A LA FLTRACION DEL PASO DE BANDA PARA RECHAZAR EL RUIDO DE BAJA FRECUENCIA Y LA SEÑAL DE LUMINANCIA SE SOMETE A LA FILTRACION MEDIANTE UNA CANTIDAD PRETETERMINADA, EN LA FRECUENCIA SUBPORTADORA DEL COLOR, PARA RECHAZAR MANCHAS O PUNTOS DE COLOR. EN UNA REALIZACION PREFERENTE, EL FILTRO SE HACE TAN SOLO CON UN INDUCTOR Y UN CONDENSADOR, EVITANDO ASI ARTEFACTOS DE PRESENTACION, CON LOS BENEFICIOS DE FIABILIDAD Y ECONOMICOS DEL COMPUTO DE PARTES MINIMO.
