Abstract
A method for selecting a decimation phase of a decimation filter includes determining a phase strength value for each phase of a plurality of phases. The quantity of phases corresponds to the decimation factor of the decimation filter. The phase strength value for a particular phase group may be representative of the sum of the magnitudes of a plurality of phase values in such particular phase group. The phase strength value for a particular phase group may represent the sum of the squares of a plurality of phase values in the group. The phase of the decimation filter is set to retain the phase with the greatest phase strength value and to filter, or decimate, the other phases.
Claims10
A method of selecting a decimation phase of a decimation filter to filter a sequence of samples, comprising the steps of:
- a) determining a plurality of phase groups;
- b) assigning each sample to one of the plurality of phase groups;
- c) calculating a phase strength value for each phase group;
- and
- d) selecting the phase group with the greatest phase strength value as the retained decimation phase.
