基于56F8013 DSP的FIR滤波器设计

Design of FIR Filter Base on 56F8013 DSP

首先介绍了FIR(有限冲激响应)滤波器的基本原理及其窗函数的设计方法,然后利用FreeScale Code Warrior开发环境自带的QEDesign lite滤波器设计工具箱进行FIR滤波器单位脉冲响应h(n)的求解,最后通过Processor Expert开发包简要描述了FIR滤波器的实际设计方法。

This paper firstly introduces the fundamental of FIR （Finite Implusion Response） filter and the design methods of Windows function; then gets the evaluation of FIR＇s unit-pulse-response h（n） by using FreeSeale CodeWarrior＇s QEDesign lite Filter Design Toolkit; at last it deerypts briefly the design methods of FIR filter by Processor Expert Toolkit.
