Filter

摘要

Method and filter for filtering a signal, in which the signal is applied to a delay line having a plurality of taps. Respective weighting coefficients of a windowing function are applied to outputs from the plurality of taps to thereby generate a plurality of weighted outputs. The method comprises repeatedly selecting, for output, whichever of the weighted outputs has the highest value.

1. A method of filtering a signal, comprising:
applying the signal to a delay line having a plurality of taps; applying respective weighting coefficients of a windowing function to outputs from the plurality of taps to generate a plurality of weighted outputs; repeatedly selecting the weighted outputs with the highest value; filtering the selected outputs over time to generate a filtered signal, the filtering including:
passing the selected outputs to a further delay line having a further plurality of taps; anddetermining an average of outputs from the further plurality of taps to generate the filtered signal; and outputting the filtered signal.
