基于LabVIEW的虚拟信号分析仪的设计与研究

针对传统信号分析仪价格昂贵,体积庞大等特点,本文从理论上介绍了信号分析仪的工作原理,提出并设计了一种基于图形化编程软件LabVIEW8.6平台的虚拟信号分析仪。该虚拟信号分析仪采用模块化设计,文中首先介绍了该虚拟信号分析仪的设计思路,并具体阐述了所设计的虚拟信号分析仪的整体功能及其所包含的各个子模块的具体功能和设计方法。最后利用计算机仿真验证了该虚拟信号分析仪的功能。本研究对于虚拟仪器的开发设计有一定的参考作用。

Design and study of virtual signal analyzer based on LabVIEW

Traditional signal analyzer is very expensive and bulk, according to the property, this paper introduces the working principle of Signal analyzer, proposes and designs a type of virtual signal analyzer based on graphical programming software LabVIEW8.6 platform. The virtual signal analyzer was designed in modules; the article described the design concept of the virtual signal analyzer, and the function of each sub-module of the design was expatiated in details. Finally, the functions of the design were showed with the computer simulation results. This work is valuable to virtual instrument design.
