基于LabVIEW的语音噪声数字滤波器的设计

摘要

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 Lab VIEW. The filter uses graphical programming language Lab VIEW 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.%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.
