Abstract
Conexión digital de regulación de fases con una conexión auxiliar, especialmente para sintonizadores de aparatos de televisión, en la que la señal de un socilador regulable está unida, a través de un divisor programable, con una primera entrada de un discriminador de fases y la señal de una fuente de frecuencia de referencia, con la segunda entrada del discriminador de fases y en que, en dependencia de la señal de salida del discriminador de fases se regula al escilador, caracterizada porque esta prevista una conexión auxiliar, maniobrada desde la salida del discriminador de fases, en que desde la señal de salida del discriminador de fases, en el caso de un error de fases se derivan una señal sincronizadora y porque con la señal sincronizadora, en una de las direccione de regulación del oscilador, se ajusta el divisor programable y en la otra dirección de regulación se regula la fuente de frecuencia de referencia, en cada caso, en un estado de salida definido.
