Abstract :
A new class of low sensitivity and efficient decimation filters based on the polyphase decomposition of IIR transfer functions is proposed. Comparisons with conventional IIR elliptic filters are presented. An illustrative example for application in passive sonar systems using real noisy data is provided.
