说明：  利用labview语言编写的声音采集程序，可以实现声音多通道的采集和分析，并显示采集到的信号波形(The sound acquisition program written in Labview language can realize the sound multi-channel acquisition and analysis, and display the acquired signal waveform)

基于LabVIEW的时域分析_自相关函数(autocorrelation function)

选择文件路径读取TDMS文件，选择是否校准，选择数据组名及通道名，对数据进行频谱分析(Spectrum analysis of the data from TDMS file.)

利用LabVIEW中的TCP/IP通讯模块实现不同机器之间的远程访问和数据传输(Using TCP/IP communication module in LabVIEW, the remote access and data transmission between different machines are realized)

说明：  基于labview平台实现振动测试，位移、速度、加速度(Based on the platform and realize the labview vibration test, displacement, velocity and acceleration)

.用产生三种不同波形，分别计算并显示它们的单边频谱及功率谱，显示低通、带通、带阻、高通四种不同的滤波效果，体会滤波器的使用。(Three different waveforms are produced, and their single side spectrum and power spectrum are calculated and displayed respectively, which show four different filtering effects, such as low pass, bandpass, band resistance and high pass, and realize the use of the filter.)

简单虚拟示波器，能调节幅值，频率，相位和偏移量四种变量。(Simple virtual oscilloscope can adjust four variables: amplitude, frequency, phase and offset.)

说明：  使用labview采集16通道数据，采集10次，保存成tdms格式，并对所有数据进行频谱分析，有效值和峭度等指标的10次趋势分析，可在趋势图中点击光标查看原始波形(Using LabVIEW to collect 16-channel data, collect 10 times, save them in TDMS format, and analyze 10 times trend of all data, such as spectrum analysis, RMS and kurtosis. Click on cursor in trend map to see the original waveform.)

说明：  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, wavelet elimination module and harmonic detection module. It's a good reference.)
