Design of M channel IIR causal stable perfect reconstruction filter banks using similarity transformation
Puduru Viswanadha Reddy, Anamitra Makur · 2004
In this work, the problem of design of M channel IIR causal stable perfect reconstruction filter banks is addressed, and design approach based on similarity transformation of the state transition matrix is presented. The analysis and synthesis polyphase matrices are constrained to be minimal. The state transition matrix of the synthesis polyphase is obtained by similarity transformation of the analysis state transition matrix. Simulation results are provided.
