labview环境下实现emd分解，而且是无密码的版本(labview environment to achieve emd decomposition , and is the version without a password )

基于labview的信号与线性系统仿真，可以实现傅里叶变换、信号平移、加减、卷积的常见信号运算(Labview based signal and linear system simulation, signal operation can achieve common Fourier transform, signal translation, subtraction, convolution)

利用LABVIEW开发的，可进行连续信号采集的程序(A program developed by LABVIEW for continuous signal acquisition)

说明：  labview与OPC通讯以欧姆龙NJ501PLC为例，希望能对大家有帮助。(Labview communicates with OPC)

利用labview实现可乐贩卖机 程序代码(Using labview achieve Coke machine code)

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 LabVIEW software, perform the following functions: 1, generates a sine wave, the superposition of a noise signal, the interface can be adjusted from the noise and the signal amplitude, frequency and other parameters, this signal as a follow-up analysis of the signal source 2. time-domain signal waveform display, click the button to display the signal amplitude spectrum, power spectrum 3, you can display a cursor on the graph, with a peak tracking, while the peak frequency, amplitude displayed on the screen. 4, click the button to display the calculated distortion (THD) signal to noise ratio (SNR), each harmonic frequency and amplitude )

一个包络检波的Labview程序，可插入到大型得项目文件中去，便于信号的分析(An envelope detection Labview program can be inserted into a large project file to facilitate the analysis of the signal)

说明：  控制转台旋转角度情况下，7路光功率计同时探测光强变化，联谊和thorlabs设备，需导入子vi。(Under the condition of controlling the rotation Angle of the turntable, the 7-channel optical power meter can simultaneously detect the change of light intensity.)

labview大数据采集，保存波形及时间参数，实时保存及波形回看并行处理，加快处理速度节省内存空间，历史记录回看符合测控应用(labview large data collection, storage and time waveform parameters, and save real-time waveforms look back parallel processing to speed up the processing speed to save memory space, looking back at the history of compliance with monitoring and control applications)

labview图形中t轴显示示系统当前时间程序，非常方便实用 (t-axis labview graphical display shows the current system time program, very handy)
