Polyphase IIR structures have proved themselves very attractive for very high performance filters that can be designed using very few coefficients. This combined with their low sensitivity to coefficient quantization in comparison to standard FIR and IIR structures makes them very applicable for very fast filtering when implemented in fixed point arithmetic. However, although the mathematical description is very simple, there exist a number of ways to implement such filters. In this paper we…

The roundoff noise and coefficient sensitivity performance of the delta operator realized recursive digital filters have been shown to be good under fast sampling, and a small but important modification is proposed to eliminate zero-input limit cycles completely if magnitude truncation quantization is used.
