(毕业论文 字数: 1117 页数:32)摘 要:文章是基于Matlab数字滤波器的设计与仿真。先说明数字滤波器实现的一般性原理,结构,设计准则及基本步骤和滤波器选择性的问题。再以窗函数法设计线性相位FIR数字滤波器为例,说明用Matlab工具软件设计数字滤波器的方法和在定点DSP上的实现。实现时,利用Matlab的FDATool或SPTool功能分别实现数字滤波系统的原理和算法,通过Matlab软件生成滤波系数,再加到特定的DSP芯片汇编程序中,在DSP集成开发环境—CCS中调试后将可执行程序写到TMS320VC5416集成电路上实时运行,结果实现了目标要求。 Abstract :This article introduces the design and emulation of digital filter based on Matlab. At first,It introduces the basic theory,structure,the rule and basic process of design and selective issue of the digital filter. Then takes the Window-Function and design Linearity Phase FIR of the digital filter for example —It introduces the method of designing the digital filter with the Matlab and the realization of integer DSP. It realizes the principle and arithmetic of the digital filter system by Matlab/FDATool or SPTool,make filter coefficient by Matlab.Then adding to the special DSP chip assembler.It also can write and circulate on the TMS320VC5416 integration circuit from the implement process after debugging in the DSP Integration Exploiture Environment—CCS. 第一章 数字滤波器概述 |
