摘　　要：频谱分析是信号处理中的一种重要分析手段,各种频谱分析设备是工程分析以及高校教学科研的常用测试仪器,传统的频谱分析仪体积庞大、价格昂贵,功能单一,本文以LabWindows/CVI为软件开发平台,完成了虚拟频谱分析仪的设计,同时验证其正确性和可行性,从而弥补传统仪器的不足。Spectrum analysis is a very important method in signal processing. Various spectrum analysis facilities are common testing machines for engineering and teaching ＆ scientific research. However, the traditional instrument is bulky and expensive with single function. In this paper, a virtual frequency spectrum analyzer based on the LabWindows/CVI software development platform was designed and its validity and feasibility were verified.
