Abstract

A system for digital voice transmission including, in the transmitter, means for extracting, from samples of a complex signal to be transmitted by the system, resonant frequency components of the signal, to leave a residual signal. There are also means in the receiver for inserting, into samples of the signal sent by the system, components of resonant frequencies that are substantially the same as the components drawn from the same samples in the transmitter. These insertion means use, at their input, only the transmitted residual signal. (Machine-translation by Google Translate, not legally binding)
