Efficient modified-Sinc decimation filters
G. Rajic, H. Babić · 2004
In this paper, for first time, we introduce non-recursive multirate architecture for modified Sinc filters. These novel structures are combined with cascaded integrator-comb (CIC) non-recursive structures and new general non-recursive architecture is proposed. Non-recursive structure can be achieved for any decimation factor that is of integer multiple form. For every stage, polyphase decomposition can be used. Polyphase decomposition combined with multistage structure result in power efficient architecture with greatly increases maximal sample rate as demonstrated with example.
