摘要

A method is provided for extracting data signals having different carrier frequencies. At least three data signals are received, a lowest carrier frequency being fL and a highest carrier frequency being fH. A first local signal is generated having a first frequency. The at least three data signals are mixed with the first local signal to generate a first mixed signal. The first mixed signal is filtered with filtering means having a pass-band of bandwidth BWF, where BWF (fH - fL), to produce a first filtered signal carrying data of a first plurality of the data signals. A second local signal is generated having a second, different frequency. The at least three data signals are mixed with the second local signal to generate a second mixed signal. The second mixed signal is filtered with the filtering means to produce a second filtered signal carrying data of a second, different plurality of the data signals.
