摘要
数字滤波器是数字系统的重要组成部分。利用文本文件实现数字滤波器存在滤波系数不易调整、开发周期长等问题。本文根据IIR的设计原理,采用LabVIEW开发平台,完成了该平台下的数字滤波器的设计,经在电力系统仿真模型上的实验证明,该滤波器能有效地滤除信号中的谐波分量,提取有用分量,并且大大提高了开发效率。
Digital filter is an important part in digital system. To settle the problems in the realization of digital filters by text software, such as： adjusting filter coefficient uneasily, and long period to develop. Infinite Impulse Response（IIR）digital filter is designed on LabVIEW according to the principium of Infinite Impulse Response.The experiment results of power system show that it can filter the harmonics and get the useful signal, which can improve the development efficiency of system .
