Abstract
A method for analog/digital conversion of a radiocommunication signal using an analog analog/digital converter preceded by variable gain amplifier, wherein the frequency band of the converted signal contains at least one useful channel, comprises steps for controlling the value of the gain of the amplifier in such a way that the power in the frequency band of the converted signal is less than a limit saturation value of the analog/digital converter. However, the power in the useful channel is substantially equal to a mean power level having a first predetermined value in the case of static propagation in the useful channel or a second predetermined value, different from said first predetermined value, in the case of dynamic propagation in the useful channel.
