Abstract

EL APARATO MUESTRA UNA ETAPA (17) DE SEPARACION DE SEÑALES SINCRONAS CON UN DISPOSITIVO (2) DE SINCRONIZACION, QUE ESTA CONECTADO A CONTINUACION EL CIRCUITO DE BLOQUEO (4) CON OTRA CONEXION A EQUIPO (5) CONVERTIDOR ANALOGICO DIGITAL, QUE MUESTRA UNA ZONA DE EXCITACION DADA. EL CIRCUITO DE BLOQUEO (4) ESTA CONFORMADO DE TAL FORMA QUE LAS SEÑALES DE VIDEO (FBAS) PUEDEN SER BLOQUEADAS EN UN POTENCIAL DIFERENTE DADO. A TRAVES DEL EQUIPO DE CONTROL (6) EL BLOQUE DE LAS SEÑALES DE VIDEO (FBAS) SE CONTROLA SEGUN EL POTENCIAL DIFERENTE DADO, PARA QUE EN UNA CANTIDAD DE SEÑALES SINCRONAS (SY,BP) LA SEÑAL DE VIDEO (FBAS) SEA TRAIDA A LA ZONA DE CONTROL EXTERIOR DEL EQUIPO (5) CONVERTIDOR ANALOGICO DIGITAL
