METHOD AND EQUIPMENT FOR TRANSMITTING A SIGNAL BY FILTERING IN A MIRROR BAND

摘要

The invention relates in particular to a method for transmitting an analogue signal in a predetermined frequency band on the basis of an initial digital signal sampled at a sampling frequency, said method comprising in particular a step of modifying the initial analogue signal so as to generate a modified analogue signal having a modified spectrum in said predetermined frequency band. According to the invention, the modifying step comprises a filtering step consisting in selecting said predetermined frequency band from said plurality of mirror frequency bands.
