Abstract
GENERADOR DE CORRIENTE DE BARRIDO DE TRAMA PARA RECEPTORES DE TELEVISION. CONSTA DE UNA UNIDAD DE MANDO (23) COMPUESTA DE UNA ETAPA DE RECUENTO DE LINEA (25), DE UN GENERADOR DE PALABRAS BINARIAS (26) Y DE UNA ETAPA DE CONVERSION DIGITAL-ANALOGICO (29), QUE CONTROLA UN INTERRUPTOR ACTIVO (7) QUE SE HACE CONDUCTOR Y NO CONDUCTOR EN CADA PERIODO DE BARRIDO DE LINEA. LA DURACION DE LA CONDUCCION SE PROPORCIONA MEDIANTE DOS MEMORIAS (51 Y 52) QUE ALMACENAN UN CONJUNTO DE PALABRAS BINARIAS Y CUYA INFORMACION PUEDE CAMBIARSE SIN PERTURBAR LA IMAGEN POR MEDIO DE UNOS CONMUTADORES (54, 54 ELEVADO, , 60, 65 Y 71).
