Abstract

CON OBJETO DE RESOLVER LOS PROBLEMAS DE LOS CIRCUITOS CONVENCIONALES DE DEMULACION DE COLOR DEL SISTEMA PAL, QUE ADOPTA UNA LINEA DE RETARDO 1H PARA RETARDAR LA SEÑAL SUBPORTADORA DE COLOR Y LOS POSIBLES ERRORES QUE PUEDAN APARECER EN LA DIFERENCIA DE SEÑALES CUANDO LA ESTRECHEZ DE LA LINEA DE RETARDO 1H ES REDUCIDA, SE PROPORCIONA UN CIRCUITO DEMULADOR DE LA SEÑAL DE COLOR QUE CONSTA DE UN PRIMER DEMULADOR 10, UN SEGUNDO DEMULADOR 20 Y DE ELEMENTOS DE RESTAURACION DE FASES. LOS ELEMENTOS DE RESTAURACION DE FASES CONSTAN DE UN SEPARADOR HORIZONTAL 31, UN GENERADOR DE PULSO 32, UN FLIP-FLOP 33, UN AMPLIFICADOR DIFERENCIAL 34, Y MECANISMOS DE CONMUTACION 35.
