Abstract

DISPOSITIVO DE POLARIZACION AUTOMATICA DEL CINESCOPIO DE UN RECEPTOR DE TELEVISION EN COLOR. LAS UNIDADES DE CONTROL O REDES DE ELABORACION DE SEÑAL CATODICA (14A, 14B, 14C) RECIBEN CADA UNA SEÑAL DE COLOR DE BAJO NIVEL (R, G, B) PROCEDENTES DE UN MATRIZ DEMODULADORA (12), QUE A SU VEZ LAS RECIBE DE UN CIRCUITO DE ELABORACION DE LA SEÑAL DE TELEVISION (10). LAS SALIDAS DE LAS REDES DE ELABORACION DE SEÑAL CATODICA (14A, 14B, 14C) ACTUAN SOBRE LOS ELECTRODOS CATODICOS (16A, 16B, 16C) SITUADOS EN EL CINESCOPIO DE COLOR (15). UNA RED DE ELABORACION DE SEÑAL CATODICA (14A, 14B, 14C) RECIBE LA SEÑAL Y LA INTRODUCE EN UNA PUERTA CONMUTADA (20), QUE LA ACOPLA O DESACOPLA A UN EXCITADOR DEL CINESCOPIO (21) SEGUN UNA SEÑAL DE CONMUTACION (VA). CON EL FIN DE CONTROLAR LA CORRIENTE DE NIVEL DE NEGRO, SE INTRODUCE UN AMPLIFICADOR (22), QUE, CONMUTADO POR DOS SEÑALES (VS, VG), ACTUA SOBRE EL EXCITADOR (21). EL SISTEMA ESTA CONTROLADO POR UNA UNIDAD LOGICA DE CONTROL (28). E
