Abstract:
1. A system, comprising: a receive tuner, tuned with respect to a first frequency, to down-convert a first modulated signal having a first bandwidth centered about the first frequency to baseband components centered about zero Hertz (Hz), and to down-convert a second modulated signal having a second bandwidth centered about a second frequency to a relatively low intermediate frequency (IF); an analog-to-digital converter (ADC) to digitize outputs of the receive tuner; and digital baseband processor including a multi-mode digital demodulator to demodulate data output from the ADC within a bandwidth that encompasses the first and second bandwidths, wherein the demodulator is digitally controllable to operate at zero Hz with respect to the first signal, and to operate at the intermediate frequency with respect to the second signal.
