A system includes an analog to digital converter (ADC) that samples an analog input signal as received by a first channel of a plurality of channels, samples the analog input signal as received by at least a second channel of the plurality of channels, and outputs a plurality of digital samples including a first set and a second set of digital samples of the analog input signal corresponding to the first channel and the second channel, respectively. A filter receives the first and second sets of digital samples, up-samples each of the first and second sets of digital samples, filters the up-sampled first set of digital samples and the up-sampled second set of digital samples, and outputs a first digital output signal and at least a second digital output signal based on the filtered first set of digital samples and the filtered second set of digital samples, respectively.
