Abstract
PARA LA EXTRACCION SINCRONIZADA (CLN) A PARTIR DE N SEÑALES DIGITALES LEIDAS A PARTIR DE CADA UNA DE N PISTAS (T {SUB,A,1} A T {SUB,A,N}) SE PROPORCIONAN N BUCLES DE BLOQUEO DE FASE (13, N). EL OSCILADOR DE TENSION CONTROLADA (21) ES COMUN A LOS N BUCLES DE BLOQUEO DE FASE. UN BUCLE DE BLOQUEO DE FASE CONSTA ADEMAS DE UNA UNIDAD DE CAMBIO DE FASE (25.N) QUE TIENE UNA ENTRADA ACOPLADA A LA SALIDA DEL OSCILADOR DE TENSION CONTROLADA (21) Y UNA SALIDA ACOPLADA A LA SEGUNDA ENTRADA DEL COMPARADOR DE FASE (17.N) EN EL BUCLE. EL CAMBIO DE FASE EN LA UNIDAD CAMBIADORA DE FASE (25.N) ESTA CONTROLADO BAJO LA INFLUENCIA DE UNA SEÑAL DE CONTROL QUE ES DERIVADA POR UN GENERADOR DE CONTROL DE SEÑAL (26.N) Y APLICADA A UNA ENTRADA DE SEÑAL DE CONTROL (29) DE LA UNIDAD CAMBIADORA DE FASE (25. N). LA UNIDAD GENERADORA DE SEÑAL DE CONTROL (26. N) ES UN ELEMENTO INTEGRADO.
