基于DSP的n阶FIR滤波器的设计

Design of the n Order FIR Filter System Based on DSP

本设计针对DSP芯片编写了基于MATLAB的FIR滤波器仿真程序FIR Simulink,可通过选择滤波器的类型及窗函数来对滤波器进行仿真,并在DSP实验箱上实现了基于TMS320VC5402的16位定点DSP芯片的FIR滤波功能,在设计中对FIR滤波器的设计方法进行了总结,找到了一种快速传递滤波器系数的方法,方便了FIR滤波器的设计。

This design has compiled FIR filter simulated program fir Simulink based on MATLAB,It can choose four types of filter and seven types of windows functions to simulate the filter,and has realized the FIR filter function in the experiment box based on TMS320VC5402’s16 fixed-point the chip of DSP.Has designed the FIR filter system electric circuit schematic diagram.Summarized the FIR filter’s designs method,and found one kind of the fast transmission method of filter’s coefficient,has facilitated the FIR filter design.
