  • In this paper IIR wavelet filter banks are efficiently designed and implemented with approximate linear-phase in pass-band. Bireciprocal lattice wave filter (BLWDF) is utilized with the replacement of one of its branches by only a unit delay. The resulting IIR filter bank is efficiently designed as wavelet transform equivalence with approximate linear-phase filters. Suitable coefficient wordlengths representations are estimated for best selection of some prescribed performance measures. A multiplierless FPGA implementation of such IIR wavelet filter is then achieved with less complexity (1%-2%) and high operating frequency(123.885-126.88MHz).
