Abstract

Un dispositivo elettronico per la conversione automatica di frequenze di campionamento, del tipo destinato a convertire una predeterminata frequenza (CKIN) di un segnale (D) campionato in ingresso in una desiderata frequenza (CKOUT) di un segnale in uscita, comprende:- un detettore (2) di fase ricevente in ingresso sia la frequenza (CKIN) di ingresso, sia quella (CKOUT) di uscita;- un blocco (3) di decodifica associato al detettore (2) per determinare un coefficiente (K) di interpolazione;- un filtro (15) interpolatore avente un ingresso (4) digitale per la codifica del segnale di campionamento e ricevente inoltre da una parte la frequenza (CKIN) d'ingresso e, dall'altra parte, un segnale digitale prelevato da un'uscita (9) del blocco (3) e rappresentante il coefficiente (K) di interpolazione;- un sincronizzatore (20), collegato a valle del filtro (15) e ricevente a sua volta in ingresso entrambe dette frequenze d'ingresso (CKIN) e d'uscita (CKOUT), avente un'uscita (18) digitale per la codifica del segnale di campionamento convertito.
