基于MATLAB与FPGA的FIR滤波器设计与仿真

Design and simulation of FIR digital filter based on MATLAB and FPGA

数字滤波器是数字信号处理领域内的重要组成部分。FIR滤波器又以其严格的线性相位及稳定性高等特性被广泛应用。本文结合MATLAB工具软件介绍了FIR数字滤波器的设计方法,并在Xilinx的FPGA器件上完成设计实现。最后,使用MATLAB和ModelSim软件对数据进行了分析,证实了设计实现的正确性与可行性。

Digital filter is an important part in the field of digital signal processing. Since its strict linear phase and higher stability properties, the FIR filter has been widely used. This paper introduced the design methods of FIR digital filter based on MATLAB, completed design and realization on the Xilinx FPGA device. Finally, analysed data using MATLAB and ModelSim software, confirmed the validity and feasibility of the design and implementation.
