| Abstract: | An approach for the design and the implementation of IIR digital filter based on FPGA is proposed.Firstly, the parameters of Butterworth band-pass filter arc computed by means of bilinear transformation method.Secondly, simulation analysis on the filter is carded out through Matlab software.Finally, module design and functional simulation are executed using Quartus Ii.Experiment results verify its effectiveness. |
