底层VI采样

labview编写的EMD分解程序 经验模态分解方法（EMD）在非平稳信号的分析和处理中起着重要的作用，为了能够方便的使用EMD方法对信号进行处理，现将LabVIEW虚拟仪器开发平台良好的用户图形界面和MATLAB软件强大的数值分析功能相结合,利用LabVIEW调用MATLAB实现EMD信号处理方法。仿真结果表明对信号进行EMD分解后，使得瞬时频率具有了物理意义，但只是对信号进行了初步处理，可根据实际需要进行相应后续处理。(the labview written EMD decomposition process.Empirical Mode Decomposition (EMD) plays an important role in the non-stationary signal analysis and processing, signal processing in order to be able to facilitate the use of the EMD method, now LabVIEW virtual instrument development platform graphical user interface and the MATLAB softwarepowerful numerical analysis capabilities combined LabVIEW calling MATLAB the EMD signal processing method. Simulation results show that the signal with EMD, making instantaneous frequency has the physical meaning of the initial treatment, but only the signal, the appropriate follow-up treatment can be based on actual needs.)

labview对制图软件生成的dxf文件内容进行更改和读取(labview for the mapping software generated dxf file content changes and reading)

基于labview的双通道数据采集处理系统，双界面，含置滤波器（巴特沃斯，切比雪夫可选），含加窗数据处理，支持数据记录并回放，用了信号源仿真，只需把信号源换成输入即可(Labview-based dual-channel data acquisition and processing system, dual interface, including home filters (Butterworth, Chebyshev optional), containing windowed data processing, data recording and playback support, with a source simulation, simply put input signal source can be replaced)

通过Labview编程实现服务器上传和下载资料(Through Labview programming server upload and download information)

说明：  读取TDMS文件，labview 2016 测试通过。(Read the TDMS file, and LabVIEW 2016 passed the test.)

labview的一个usb和visa通讯的很好的一个参考例子(LabVIEW a USB and visa communication is a good example of reference)

说明：  利用Labview采集8路信号数据，带注释(Using Labview to collect 8-channel signal data with annotations)

自功率谱是分析非平稳信号频谱的重要手段。对于非平稳信号来说，利用自功率谱分析能够更容易找到信号中能量聚集区域，对信号中的频率分布有更好的了解。本文件中将其制作成独立子VI方便程序直接调用。(Self power spectrum is an important method to analyze the spectrum of non-stationary signals. For non-stationary signals, it is easier to find the energy accumulation region in the signal by using self power spectrum analysis, and better understand the frequency distribution in the signal. This document will be made into an independent sub VI convenience program to call directly.)
