Based on the introduction of the structural characteristics and the basic principles of finite im- pulse response (FIR) digital filter, this paper gives an efficient proposal of implementation of FPGA-based case. Such a proposal uses MATLAB tools in the case to determine filter coefficients, and VHDL language to get a 16-order constant coefficient FIR filters. And then it takes use of MAX + plus II to simulate filters, whose results meet the performance design requirements.
