Abstract

CIRCUITO DE REGULACION DE LOS NIVELES DE REFERENCIA DE LOS COLORES EN UN RECEPTOR DE TELEVISION EN COLORES. A UN FILTRO CAMPANA (10) LLEGA LA SEÑAL VIDEO-COMPUESTA (S) RECIBIDA, QUE PREVIAMENTE SE HA DEMODULADO EN AMPLITUD, Y ES COMPENSADA LA MODULACION DE AMPLITUD, Y ES COMPENSADA LA COMULACION DE AMPLITUD INTRODUCIDA EN LA EMISION, A LA VEZ QUE SON SEPARADAS LAS SUPORTADORAS MODULADAS. ESTAS SE APLICAN A UN CIRCUITO DE CONMUTACION (20) QUE LLEVA APLICADA LA SEÑAL DE UN OSCILADOR DE CUARZO (30), Y ES MANDADO POR UNA SEÑAL A LA FRECUENCIA DE TRAMA. LA SALIDA VA A UN DECODIFICADOR (40). DE LAS DOS VIAS DE SALIDA DE ESTE SE TOMA UNA CUALQUIERA (R-Y) Y, A TRAVES DE DOS CIRCUITOS (50, 60), SE REINSERTAN LOS NIVELES DE REFERENCIA EN LAS SEÑALES DE SALIDA POR MEDIO DE UNOS CIRCUITOS DE CONMUTACION (70, 80) MANDADOS POR UNA SEÑAL DE MANDO (E). DE APLICACION EN TELEVISORES QUE FUNCIONEN POR EL PROCEDIMIENTO SECAM.
