Abstract

Il sistema di trasmissione digitale di segnali analogici consiste nel convertire il segnale analogico da trasmettere in due impulsi digitali la cui durata é proporzionale rispettivamente al segnale stesso e al suo fondoscala. L'informazione così trasmessa può essere riconvertita nel valore originale semplicemente facendo il rapporto tra la durata dei due impulsi digitali.
