Abstract

CIRCUITO QUE PROPORCIONA UNA SEÑAL DE FASE BLOQUEADA EN UNA SEÑAL DE SINCRONIZACION INCLUIDA EN UNA SEÑAL DE VIDEO RECIBIDA, QUE INCLUYE UN PRIMER CIRCUITO DE BLOQUEO DE FASE (16,44,46;16,46'',204) Y UN SECUNDO CIRCUITO DE BLOQUEO DE FASE O DE CONTROL AUTOMATICO DE FRECUENCIA (26,44,46;26,4446'',204). EL PRIMER CIRCUITO DE BLOQUEO DE FASE TIENE UNA PLURALIDAD DE INTERVALOS DE BLOQUEO. EL SEGUNDO CIRCUITO DE BLOQUEO DE FASE O DE CONTROL AUTOMATICO DE FRECUENCIA, QUE TIENE UNA CARACTERISTICA DE SALIDA CON UNA UNICA CURVA EN S, TIENE UN INTERVALO DE BLOQUEO DE MAYOR ANCHURA EL SEGUNDO CIRCUITO DE BLOUQEO DE FASE O DE CONTROL AUTOMATICO DE FRECUENCIA ESTA DOTADO DE UNA SEÑAL HORIZONTAL DE SINCRONIZACION SEPARADO EN UN CIRCUITO SEPARADOR DE SINCRONIZACION A TRAVES DE UN FILTRO PASABANDA. EL PRIMER CIRUITO DE BLOQUEO DE FASE ES ALIMENTADO DIRECTAMENTE CON UNA SEÑAL DE SINCRONIZACION HORIZONTAL EXTRAIDA DEL CIRCUITO SEPARADOR DE SINCRONIZACION. EL PRIMER CIRCUITO DE BLOQUEO DE FASE COMPARTE UN OSCILADOR CONTROLADO DE VOLTAJE (46;46'') Y UN DIVISOR DE FRECUENCIA (46;204) CON EL SEGUNDO CIRCUITO DE BLOQUEO DE FASE O DE CONTROL AUTOMATICO DE FRECUENCIA. ESTE CIRCUITO DE SINCRONIZACION DE FASE INCLUYE ADEMAS UN CIRCUITO (48) PARA DETECTAR LA SINCRONIZACION/DESINCRONIZACION DE UNA SALIDA DEL CIRCUITO DIVISOR DE FRECUENCIA CON LA SEÑAL DE SINCRONIZACION HORIZONTAL SEPARADO/EXTRAIDO EN EL CIRCUITO SEPARADOR DE SINCRONIZACION, Y UN CIRCUITO CONMUTADOR (42) PARA ACTIVAR UNO DELPRIMER CIRCUITO DE BLOQUEO DE FASE Y DEL SEGUNDO CIRCUITO DE BLOQUEO DE FASE O CONTROL AUTOMATICO DE FRECUENCIA EN RESPUESTA A UNA SALIDA DE ESTE CIRCUITO DETECTOR DE SINCRONIZACION.
