| 摘 要： | 有限冲激响应(FIR)滤波器是数字信号处理系统中最基本的元件,具有严格的线性相频特性,同时其单位抽样响应是有限长的,系统稳定。阐述了FIR的基本原理,并进行了MATLAB仿真。基于TI公司的TMS320VC5402 DSP硬件平台,设计了FIR低通滤波器。采用C语言算法,利用集成开发环境代码调式器(Code Composer Studio,CCS)分别观察了输入和输出波形,验证了此算法的准确性和高效性,对信号处理及信号传输有重要的研究意义。

| Abstract: | Finite impact response(FIR) filter is a basic component in digital signal processing system,of which the phase and frequency have strict linear relation and the unit sampling response is finite.In this paper,we discuss the basic principle of FIR filter,and implement MATLAB simulation.We design FIR lowpass filter based on TMS320VC5402 DSP.The input and output waveform is observed by using C-language algorithm and integrated development of environmental code composer studio(CCS).The accuracy and high efficien... |
