用LabVIEW编制一个完整应用软件，完成以下功能： 1、产生一个正弦波，叠加一个噪声信号，从界面上可以调整噪声和信号的幅度、频率等参数，此信号作为后续分析的信号源； 2、显示信号的时域波形，点击按钮可以显示信号的幅度谱、功率谱 3、图形上可以显示光标，具有峰值跟踪功能，同时将峰值频率、幅度显示在界面上。 4、点击按钮可以计算显示信号的失真度（THD）、信噪比（SNR）、各次谐波的频率和幅度；-Preparation of a complete application using

Power system harmonic detection based on Labview and Matlab

In order to solve the power quantity problem of negative sequence current and harmonic current in high-speed railway, railway static power conditioner (RPC) was adopted. RPC contains two inverters which are connected with each other by sharing a DC c

准备电赛时使用Labview制作的电能监控系统，分为CD主页面、采集数据、电压偏差模块、控件1、小波去躁模块、谐波检测模块六部分。是很好的参考资料。(The power monitoring system made by Labview is used to prepare electric races. It is divided into six parts: CD main page, data collection, voltage deviation module, control 1
