Abstract

Apparecchio ricevente, atto a ricevere delle informazioni trasmesse da un fondo di pezzo petrolifero e di gas, ad una superficie, per mezzo di onde elettromagnetiche. L'apparecchio ricevente comprende un'antenna ricevente, atta a ricevere un segnale emesso dal pozzo petrolifero, un rivelatore di rumori, atto a rivelare i rumori di corrente che riceve la antenna ricevente, ed un dispositivo antirumori adatto ad eliminare tutte le componenti di rumori estranei che vengono ricevute dall'antenna ricevente per mezzo del confronto fra un segnale di uscita di provenienza dall'antenna ricevente, con un segnale in uscita proveniente dal rivelatore dei rumori. Il dispositivo antirumori è un dispositivo cancellatore dei rumori che usa dei filtri paralleli adattativi, e che comprende anche un certo numero di filtri adattativi montati in parallelo, ed un addizionatore per sommare i segnali di uscita provenienti dai vari filtri adattativi, oltre ad un sottrattore, alle scopo di sottrarre un segnale d'uscita da un segnale d'entrata principale.
