Design of High Accuracy IIR Floating Digital Wave Filter Based on FPGA
Fengxin Liu · Microcomputer Information · 2009
This article offerd a design method of Four_step elliptical IIR digital wave filter using the Floating-point multipliable mod-ule on the FPGA.Compared with the similar kind of design which is using the LPM multipliable module,this design 's structure is simple and to expand the structure is more easily.The operation result of this design have a high accuracy compareing with the re-sult of Matlb operation.
