Abstract
This paper concentrates on designing two-channel filterbanks (FBs) with rational sampling factors based on using infinite-impulse response (IIR) filters. In order to generate FBs having a low implementation complexity, a special structure for the IIR filters is utilized, which enables one to evaluate the recursive part of the IIR filters at the subband sampling rate, that is, at the lowest sampling rate in the FB. A method for designing such FBs is proposed and the implementation efficiency of these FBs is demonstrated by means of examples.
