Abstract

Firstly,this paper introduced the theory and the common implementation methods of finite impulse response(FIR) digital filter.Then it put forward an efficient design method for FIR digital filter,the scheme used FPGA chip and Quartus II,DSP Builder softwares to realize the filter.Simulation results show the FIR filter has the characters of fast operation and good real time,is superiror to the traditional ones.
