ABSTRACT:
The invention relates to a transmitting device limiting the out-of-band interferences. The modulation is done with or without inversion of the spectrum. Next, frequency transposition is done in supradyne or infradyne fashion such that the parasitic effects originating from the modulation are always situated in the frequency band allocated for transmission. The invention relates to the transmission method, on the one hand, and to the transmission device, on the other hand.
