ABSTRACT:
A method of filtering digital signals having a high dynamic range includes splitting the sampled input signal into at least two portions addressing each of the portions to a respective program filter, and performing each filtering operation in parallel and independently, and reconstituting an output signal by summing together the digital outputs from each filter.
