The introduction of this paper is in height of the method of the highstep IIR digital adopting cascade structure of wave filter in realizing on FPGA. The analysis tool( FDATool) and the Matlab design of wave filter in signal handling tool case are used to design the IIR wave filter that doesn′ t be quantified in accordance with application requirement very conveniently, and it is further described with VHDL language, through compiling, function emulatation,synthesis and can be realized on FPGA after sequential emulatation. This design development is good, and in actual use, the proper modificaion of peripheral parameter frequency that changes wave filter respondence can be realized according to different requirements on the FPGA of different scales.
