读取txt的文本的二列数据，实现冲击响应谱分析和功率谱分析(Read txt text two data to achieve shock response spectrum analysis and power spectral analysis)

说明：  LabView信号处理算法，包括功率谱，幅值谱，小波分析等(LabVIEW signal processing algorithm)

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.)
