The transmitter comprises a multiplication circuit which receives on the one hand the digital signals and on the other hand, from a frequency generator, a signal with the timing of the digital signals. The signal obtained by this multiplication makes it possible to generate in the frequency modulator of the transmitter a carrier line which does not suffer from phase noise. Thus, it is possible to perform a coherent demodulation in a receiver which cooperates with the transmitter.
