Patent ID: 8503890

Claim:
A signal processing device comprising: a filter module for receiving a multi-channel signal comprising: at least two band pass filters configured for filtering the multi-channel signal and outputting a single channel signal respectively; a first selector selectively coupled to one of the band pass filter to output the selected single channel signal; a demodulation module coupled to the filter module, configured for demodulating the selected single channel signal and outputting a demodulated signal, the demodulation module further comprising: a demodulator; at least two resonators corresponding to the band pass filters; a second selector configured between the demodulator and the resonators configured for selectively coupling the demodulator with the resonators; and a band control module coupled to the first selector and the second selector configured for controlling the coupling of the first selector and the band pass filters and the corresponding coupling of the demodulator and the resonators by the second selector.
