This paper discusses the design and realization of digital filtering system based on FPGA. Circuit mod-ules, including A/D sampling control, FIR filter based on distributed algorithm and frequency analysis circuit baaed on FFT IP core, which are the major parts of the system, are designed in the chip according to the digital filtering principle, and the simulation waveforms in Quartus Ⅱ are given too. The experiment results show that the method dis-cussed in the paper has the advantages of high speed and flexibility, and FPGA could be widely used in the high speed digital signal processing research areas.
