In one embodiment, the present invention is directed to an apparatus configured to perform channel filtering operations digitally, to reduce area and power consumption as compared to analog filtering. After passive filtering of downconverted analog baseband signals, the signals are provided to digitization circuitry to convert the filtered baseband signals into digital signals. Then a digital circuit, which may be implemented as a digital signal processor (DSP), may channel filter the digital signals and provide the filtered digital signals to conversion circuitry to convert the channel filtered digital signals back to analog signals.
