Abstract

Improved modulation procedure of the type consisting of sampling a sinusoidal carrier wave and a modulated signal at the same frequency and performing, at each sampling time, the product of the sample obtained on the carrier wave by the sample obtained on the modulated signal, characterized in that the sampling frequency is four times the frequency of the carrier wave, and because the sampling phase is chosen to obtain in a period of the carrier wave two positive samples followed by two negative samples, these four samples being the same in module.
