In accordance with embodiments of the present disclosure, a processing system comprising may include a plurality of processing paths and a filter. The plurality of processing paths may include a first processing path and a second processing path, wherein the first processing path is configured to generate a first digital signal based on an analog input signal and the second processing path is configured to generate a second digital signal based on the analog input signal. The filter may have a corner frequency and may be configured to generate a filtered digital output signal combining spectral components of the first digital signal lower than the corner frequency and spectral components of the second digital signal higher than the corner frequency to generate a filtered digital signal.read more
