利用LabWindows/CVI实现SCPI指令集的方法(Using LabWindows/CVI implementation SCPI command set)

低通滤波器的labview模型，用于滤波消除系统的noise(low pass filter labview model)

说明：  这个包中包含各种子vi，可以完成对线阵CCDTD1304的数据采集功能(Can complete the data reading function of the line CCD)

labview中usb raw设备的读取和写入程序 非常有用(labview usb raw device in the read and write process is very useful)

这是一款基于Labview的变声器，我用的版本是Labview2011，软件的主要目的是改变输入的声音(This is a Labview-based voice changed, I used version is Labview2011, the main purpose of the software is to change the input voice)

说明：  用于信捷PLC与Labview之间的通信，可以作为学习的初版(Used for the communication between Sinjie PLC and Labview, it can be used as the first edition of learning.)

说明：  客户觉得TestStand界面复杂，希望一个简单的界面即可进行序列执行，采用LabVIEW调用TestStand引擎可实现快速设计，将TestStand拆解到LabVIEW。 然而，这样做需要设计大量回调函数，开发较费时间，项目对时间要求很严格，且投入不多，故希望有快速解决方案。 为此，设计时希望LabVIEW可以充当一个辅助软件，可配置和控制执行，进行简单数据交互，执行还是TestStand进行(The customer thinks that TestStand interface is complex, and hopes that a simple interface can be used for sequence execution. Using LabVIEW to call TestStand engine can realize rapid design and disassemble TestStand to LabVIEW. However, to do this, a large number of callback functions need to be designed, which takes a lot of time to develop. The project has strict time requirements and little investment, so we hope to have a fast solution. Therefore, it is hoped that LabVIEW can be used as an auxiliary software in the design, which can be configured and controlled for execution, simple data interaction, execution or TestStand)

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.)
