In this paper. Bireciprocal Lattice Wave Digital Filters (BLWDFs) are utilized in an  approximate linear-phase in pass-band design of  order IIR wavelet filter banks (FBs). These filter banks are efficiently designed by replacement one of  branches for (BLWDFs)  by only a unit delay. The coefficients of the designed filter are achieved by simulating the IIR response suggested in [1]. The design is  first simulated using Matlab programming in order to investigate the resulting wavelet filter properties and to find the suitable wordlength for the BLWDFs coefficients. FPGA implemtation of the proposed IIR wavelet filter bank is also achived for three levels with less complexity and high operating frequency.
