Abstract

CIRCUITO PARA SEPARAR LAS COMPONENTES DE UNA SEÑAL PAL. LA SEÑAL DE CROMINANCIA COMPUESTA (F) ES APLICADA A UN PRIMER PASO COMBINADOR (IO) A TREVES DE UN PRIMER DISPOSITIVO DE RETARDO (21). TAMBIEN ES APLICADA A UN SEGUNDO PASO COMBINADOR (24) A TRAVES DE UN SEGUNDO DISPOSITIVO DEL RETARDO (22), SIENDO ESTE RETARDO CON RELACION AL PRIMER DISPOSITIVO (21) DE UN MULTIPLO DEL PERIODO DE LINEA. ADEMAS, ES APLICADA DIRECTAMENTE A AMBOS PASOS COMBINADORES (23, 24). DE ESTE MODO, LOS TERMINALES DE SALIDA (25, 26) PROPORCIONAN COMPONENTES DE LA SEÑAL DE DIFERENCIA DE COLOR SEPARADAS.
