基于FPGA的16阶FIR滤波器的设计与实现

Design and implementation of 16 order FIR filter based on FPGA

分析FIR滤波器的结构特点和基本原理,提出FPGA实现数字信号处理的方案.基于Matlab用窗函数法对FIR滤波器进行了设计,确定了滤波器的系数,最后用VHDL语言实现了16阶常系数FIR滤波器,并用QuartusⅡ软件对滤波器进行了逻辑仿真,结果符合设计预期.

The configuration and keystone of the FIR filters were analyzed in this article, it advanced a project of DSP based on FPGA. The article designed a FIR filter by windows in Matlab and ascertained coefficients of the FIR. A 16 - steps invariable coefficients FIR filter was implemented with the VHDL code, furthermore, the filter was simulated in logic by QuartusⅡ. The results showed that the anticipation of design could be reached.
