| 摘 要： | 介绍了基于LabVIEW平台的数字抽取滤波器的设计。该方法是对高采样率的数据进行低通数字滤波，然后对结果用1／K倍重新采样，将数字信号频带压缩K倍，从而实现动态测试较大的动态范围要求和划分频带要求，数字抽取滤波器的设计包含调制，数字滤波和抽取三方面，LabVIEW是一种基于图形编程语言（G语言）的开发环境，采用交互界面设计，模块化编程，该滤波器也是作者正在研制的动态测试分析虚拟仪器的一个重要组成部分。本文给出了在LabVIEW平台上所进行数字抽取滤波器的设计原理，仿真结果和在动态数字信号分析中的应用。

| Abstract: | A method to implement digital decimation filter based on LabVIEW is introduced. The sense of decimation filter may filter high sampling rate data with low pass filter, thus resample the result data with 1/ K sample rate. The filter can be used to divide frequency band and realize great dynamic range in dynamic test. Digital decimation filter design and implementation consist of three steps including modulation, digital filtering and decimation. With the LabVIEW a alternate interface is designed to view how design parameters to affect filter performance. This paper provides design principle, simulational result and application of decimation filter. |
