Abstract

A system for the transmission of a signal by means of a modulated wave, characterized in that the transmitter has, after the demodulator, a filter that further attenuates the central frequencies in relation to the lateral frequencies of the frequency spectrum of the wave supplied by the modulator and because the receiver has, in front of the demodulator, an element whose characteristic, "relative amplitude/frequency" is in the range of useful frequencies, the inverse of the characteristic of said filter (Machine-translation by Google Translate, not legally binding)
