摘　　要：针对传统的数字滤波器所采用的编程方法存在编写代码复杂、可移植性差等问题,提出了一种基于LabVIEW的语音噪声数字滤波器的设计方案。该滤波器采用图形化编程语言LabVIEW 8.6实现语音信号的滤波、实时测量与保存、报警等功能,与传统的滤波器相比,具有开发经费节省、开发过程简单、扩展功能方便和操作使用便易等优点。In view of problems of complex code program and poor portability in programming method of traditional digital filter,the paper proposed a design scheme of digital filter for voice noise based on LabVIEW.The filter uses graphical programming language LabVIEW 8.6 to realize functions of voice signal filtering,real-time measurement and storage,alarm,which has characteristics of low development fund,simple development process,convenient extend function and easy operation and usage compared with traditional filter.
