分享下labview图形显示控件，非常好用的呀(Share the labview graphical display control, very easy to use, suitable for LabVIEW beginners)

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.)

声音信号的功率谱分析(LABVIEW8.2),对声信号进行功率谱分析(Power spectrum analysis of sound signals (LABVIEW8.2))

虽然简单，但是基础，用labview实现的01随机数并生成直方图(Though simple, but basic, with labview achieve 01 random numbers and generate a histogram)

利用VISA去控制GPIB串口通信，最终实现与频谱仪，电源，示波器等相互之间通信(VISA to control GPIB serial communication, and ultimately with the spectrum analyzer, power supplies, oscilloscopes, and other mutual communication between)

一个上位机测控软件，采样Labview2011编写，主要功能的和下位机通信，向下位机下发控制指令，并实时显示处理下位机上传的采集数据。(A PC control software, sampling Labview 2011 write, and communicate the main function of the lower down-bit machine control commands issued, and real-time data acquisition display processing lower computer to upload.)

说明：  使用Labview平台计算误码率，绘制误码率曲线，用于通信系统仿真。(Calculate the bit error rate and reconstruct the bit error rate curve)
