METHOD OF SAMPLING AN ANALOGUE RADIOFREQUENCY SIGNAL

摘要

This invention relates to a method for sampling an analogue radio frequency signal comprising reception of the analogue radio frequency signal, sending of the received signal on two analogue channels (I, Q), each channel performing a first signal sampling operation (9, 10), including a filtering step (13, 14) eliminating signal frequencies that could fold on the useful signal during sampling such that the sampled signal represents a filtered version of the received signal, the said method being characterised in that the sampling frequency (Fsl) is taken to be equal to the frequency (Fc) of the signal carrier divided by a factor Ndivl+1/2, Ndivl being an integer number, to bring the useful signal to half of the sampling frequency after sampling.
