摘要
本文指出了数字滤波器是现代数字信号处理的重要基础,阐述了数字滤波器的基本原理。介绍了利用TI公司提供的数字滤波函数库filtertool进行数字滤波器设计的方法,并给出了在MATLAB软件中实现的滤波器设计效果波形和实验波形。实验表明,此方法方便实用,可以很好地在TMS320F2812上进行数字滤波。
The paper points out that digital filter is a fundamental part in modern digital signal processing and expounds the principle of digital filter. A solution of digital filter design used digital filter function library filter tool provided by TI company is introduced. The effect wave and the experiment wave are given in software MATLAB. Experiment results show that this method has good facility and utility . It is proved that this filter has good effect on TMS320F2812.
