Abstract
A technique includes receiving a signal spectrum that includes a plurality of channels within a first frequency range. The technique includes receiving a selection signal that identifies at least one desired channel to be tuned. The technique includes providing an oscillator that has a second frequency range that is substantially the same as the first frequency range and controlling the oscillators to generate one of a plurality of coarse-tune analog mixing signals. The signals substantially span across the second frequency range and each depends upon the location of the desired channel within the signal spectrum. The technique includes mixing the signal spectrum with the selected coarse-tune analog mixing signal to generate a coarsely tuned signal spectrum. The technique includes digitally processing the coarsely-tuned signal spectrum to fine tune the desired channel and to produce digital baseband signals for the desired channel.
