ABSTRACT:
A method of digital filtering and a digital filter having a filter response with a predetermined filter order. The filter response produces a predetermined set of filtered output samples defining an output signal from a received input signal. The difference between the power associated with the input signal and the power associated with the output signal is calculated. The filter order of the filter response is varied based on the calculated difference of power in order to change the filter response.
