| Summary: | This paper describes the application of filter sharpening method to the
modified comb filter (MCF) in the case of decimation factor, which is product
of two or more positive integers. It is shown that in the case of multistage
decimation with MCF, filters in each stage are also MCF. Applying the
sharpening to the decimation filter in the last stage provides very good
results, with savings in the number of operations comparing to the case of
sharpening of the complete filter. Direct-form FIR polyphase filter structure
is proposed for the filters in each stage. |
