Design of two-channel linear phase IIR PRQMF banks based on the approximation of FIR filters
E. Tufan, V. Tavşanoglu · 2002
This paper presents an algorithm to design two-channel linear phase IIR PRQMF (LP IIR PRQMF) banks. This algorithm is based on the approximation of the FIR by IIR digital filters matching a finite portion of the impulse response and the autocorrelation coefficients of a given FIR filter.
