摘　　要：信号处理几乎涉及到所有的工程技术领域,而频谱分析正是信号处理中一个非常重要的分析手段。一般的频谱分析都依靠传统频谱分析仪来完成,价格昂贵,体积庞大,不便于工程技术人员的携带。本文设计的基于LabVIEW7.1设计的虚拟频谱分析仪,用软件代替硬件,价格低,使用方便,利用它工程技术人员可轻松完成现场信号的采集、处理及频谱分析。Signal processing involved in almost all areas of engineering, and analysis of the spectrum signal processing is a very important means of analysis. The general analysis of the spectrum have to rely on traditional spectrum analyzer which is expensive, bulky and not easy to bring for the engineers and technicians. The virtual spectrum analyzer was designed based on LabVIEW7.1 in this paper with software instead of hardware, by which the engineers can easily complete the signal acquisition, processing and analysis of the spectrum..
