Method for processing a received broadcast signal and a system therefore

摘要

A System (1) for processing an analogue intermediate frequency signal with variable frequency comprises sampling means (5) for sampling the analogue intermediate frequency signal on the basis of a variable sampling rate to obtain a digital intermediate frequency signal, and mixing means (6) being connected to the sampling means for frequency shifting of the digital intermediate frequency signal on the basis of a variable shifting rate to obtain a digital baseband sign al, wherein the shifting rate is adjustable so that the digital intermediate frequency signal is shifted into a predetermined frequency range. This allows to process analogue intermediate frequency signals with any frequency, and saving energy at the same time.
