Abstract
The invention concerns a demodulator of an amplitude-modulated signal (Vdb), characterised in that it comprises a peak detecting cell (DCR) capable of extracting the reference modulating signal (Vpeak1) of the modulated signal (Vdb); a first demodulator (FE) adapted to detect the peak of the reference modulating signal (Vpeak1) to generate a high comparison threshold and locate the start of the modulation, a second demodulator (RE) adapted to detect a trough of the reference modulating signal (Vpeak1) to generate a low comparison threshold and locate the end of the modulation; a logic processing unit capable of supplying the demodulated signal (Vdemod).
