Abstract

CIRCUITO DE MANDO DE BARRIDO DE TRAMA EN MODO CONMUTADO PARA TELEVISION. UNA CARGA (1), QUE INCLUYE UN DESCIADOR VERTICAL (DV), ESTA CONECTADA A LOS BORDES DE UN CIRCUITO GENERADOR (2) DE UNA SEÑAL EN DIENTE DE SIERRA. ESTE RECIBE LA SEÑAL DE UN INTERRUPTOR ACTIVO (IS1), CONTROLADO POR UN CIRCUITO INTERCARA (10), QUE SE SITUA EN SERIE CON EL SECUNDARIO (S1) DE UN TRANSFORMADOR (TL). EL CIRUCITO INTERCARA (10), RECIBE SEÑAL DE UN CIRCUITO DE MANDO DE RELACION CICLICA (3). POR UN CIRCUITO SEPARADOR DE TRAMA (9) ENTRA LA SEÑAL DE SINCRONIZACION TOMADA SOBRE LA SEÑAL DE VIDEO Y DESPUES DE UN PROCESO DE TRANSFORMACION A TRAVES DE VARIOS CIRCUITOS DE MEZCLA EN UN CIRCUITO DE SUBORDINACION (7) CON EL PROCEDENTE DE UNA RESISTENCIA DE MEDIDA (RM). LA SALIDA DE ESTE Y LA PROCEDENTE DE UN CIRCUITO DE SUBORDINACION ESTATICO (6) SE UNEN, LLEGANDO JUNTO CON LA PROCEDENTE DE UN CIRCUITO GENERADOR DE DIENTES DE SIERRA (4) EN EL MANDO DE RELACION CICLICA (3). EL CIRCUITO GENERADOR DE DIENTES DE SIERRA (4) RECIBE ALIMENTACION DE OTRO SECUNDARIO (S2) DEL TRANSFORMADOR (TL). 4
