Abstract

Viene qui descritto un metodo per la codifica e la decodifica differenziale ed ai relativi circuiti.La codifica differenziale è un particolare tipo di codifica che invece di codificare direttamente un segnale di ingresso effettua la differenza di questo segnale con un suo segnale predetto. Ciò permette di ridurre l'informazione da trasmettere.L'invenzione propone un metodo in grado di ridurre ulteriormente la ridondanza del segnale e quindi l'informazione da trasmettere.
