Abstract
The invention relates to a method of demodulating a signal (I, Q) that has a main component and harmonics. According to the invetion, this method includes the following of a selection of one of the harmonics, and a demodulation of the selected harmonic. The invention enables the elimination of a parasitic component introduced by the demodulation into the demodulated signal SD without altering the data carried by the signal SD.
