Abstract

CIRCUITO DE SINCRONIZACION PARA RECEPTOR DEL TELEVISION. EL CIRCUITO, MEDIANTE UNA SERIE DE COMPONENTES, ESTABLECE UNA DISTINCION ENTRE LAS SEÑALES RECIBIDAS. SI LA SEÑAL ENTRANTE ES UNA SEÑAL DE TELEVISION NORMAL, UN PASO DE COINCIDENCIA DE CAMPO (23) NO ES ALTERADO, PUES NO HAY VARIACION EN EL ESTADO DE SINCRONISMO DE FASE; LA SALIDA DE UN CONTADOR (24) ES EL ESTADO LOGICO 0, Y EN CORRESPONDENCIA, UN CONMUTADOR (29) HACE QUE LOS IMPULSOS GENERADOS EN UN DIVISOR (21) LLEGUEN A UN PASO (30) DE SALIDA DE CAMPO, QUE ACTUA SOBRE LA BOBINA DE DEFLEXION VERTICAL DEL TUBO DE IMAGEN. SI LA SEÑAL ENTRANTE NO ES UNA SEÑAL NORMAL, EL ESTADO DE LOS COMPONENTES VARIA, GENERANDOSE UN MODO DE FUNCIONAMIENTO DE SINCRONISMO EXTERNO, HASTA QUE LA SEÑAL VUELVA A SER NORMAL. A
