FIR数字滤波器的设计与实现

Design and Realization of a Digital FIR Filter

摘要: 本文在MATLAB环境下采用窗函数法设计了一个低通滤波器，并在CCS集成开发环境下进行了仿真，给出了在DSP芯片上进行了实现的过程。FDATool工具箱也被用来进行滤波器的设计，可方便地根据设计要求随时改变参数，以使滤波器达到最优化。

Abstract: A low-pass filter is designed under MATLAB environment in this paper by using the window function method. Simulation test and implement are finished under the CCS integrated development environment, and the details of realization process on the DSP chip are also presented. FDATool toolbox is also used for filter design so that the parameters can be changed at any time according to the design requirements, which will make the filter achieve the optimization.
