#CMT# #/CMT# The method involves delivering an incident signal to a low noise amplifier stage (LNAI), and connecting a current output of the stage to a storage capacitor in order to deliver a current signal to the capacitor, during a part of a half period of each period of a periodic signal. A signal transposed into frequency is obtained at the capacitor. The voltage of the current output is initialized to a value equal to that of the voltage of the capacitor, during the occurrence of each part of the half period. #CMT# : #/CMT# An independent claim is also included for a device for processing an incident signal, comprising a generating unit. #CMT#USE : #/CMT# Method for processing a radio frequency signal e.g. digital terrestrial TV signal or signal transmitted in a frequency multiplexing transmission system, by frequency conversion, in a radio frequency signal receiver (claimed). #CMT#ADVANTAGE : #/CMT# The method permits improvement of the frequency conversion of the signal, while limiting degradation of gain. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic block diagram of an internal structure of an incident signal processing device.
