Abstract
UNA SEÑAL (LOCK-ALARM) DE UN DETECTOR DE BLOQUEO DE UN SINTETIZADOR INDICA EN UN PRIMER ESTADO QUE UN CIRCUITO ESTA BLOQUEADO, Y EN UN SEGUNDO ESTADO QUE EL CIRCUITO ESTA DESBLOQUEADO. EL SINTETIZADOR PUEDE ACTIVARSE TEMPORALMENTE APAGANDO LA TENSION DE FUNCIONAMIENTO DE UN OSCILADOR CONTROLADO POR TENSION POR MEDIO DE UNA SEÑAL DE CONMUTACION (CNTRL). EL CIRCUITO DE ALARMA DEL SINTETIZADOR DE LA INVENCION COMPRENDE UN PRIMER DETECTOR (1), CUYO ESTADO DE SALIDA CAMBIA CON UN RETARDO DE TIEMPO, EN RESPUESTA AL CAMBIO DE LA SEÑAL (LOCK-ALARM) DEL DETECTOR ENVIADA AL DETECTOR, Y UN SEGUNDO DETECTOR (2), EL ESTADO DE CUYA SALIDA CAMBIA CON UN RETARDO DE TIEMPO EN RESPUESTA AL CAMBIO DE LA SEÑAL DE CONMUTACION (CNTRL) ENVIADA AL DETECTOR, Y UN DISPOSITIVO (3) QUE GENERA LA SEÑAL DE ALARMA, EL DISPOSITIVO SUMINISTRA LA SEÑAL DE SALIDA (SYNTE-ALARM) DEL CIRCUITO DE ALARMA EN RESPUESTA A LAS SEÑALES DE SALIDA DE LOS DETECTORES. SELECCIONANDO LOS TIEMPOS DE RETARDO APROPIADOS PARA EL DETECTOR, ES POSIBLE CONSEGUIR EL FUNCIONAMIENTO DESEADO.
