说明：  基于.Net的DirectShow LIB包，可以用于Labview调用DirectShow，实现对相机的控制(The. Net-based DirectShow LIB package can be used to call DirectShow by Labview to control the camera.)

PID control。Labview中搭建的程序。经典！！(A program of PID control in Labview.)

基于LABVIEW的虚拟频谱分析仪，可以对任意信号以及采集卡采集到的信号进行频域分析，同时还加入了时域分析，使功能更为强大。(LABVIEW-based virtual spectrum analyzer can be arbitrary signals and the signal acquisition card for frequency domain analysis, and also joined the time-domain analysis, so that more powerful.)

利用LabwindowsCVI实现PC机与智能仪器串口通信！！！！！！！！(PC, using LabwindowsCVI realize serial communication with intelligent machines! ! ! ! ! ! ! !)

说明：  虚拟示波器的设计， 基于LabVIEW的虚拟示波器设计 (Virtual Oscilloscope)

利用labview连接数据库，并用SQL查询访问数据库。对于初学者有很好的帮助作用。(LABVIEW SOL)

LabVIEW对波形求导，求导后的斜率用波形显示(LabVIEW is used to derive the waveform, and the slope after derivative is displayed in waveform)

本文关于labview中模拟输入、模拟输出、数字I/O功能，希望能够对大家有所帮助。(This article about labview analog input, analog output, digital I/O functions, hoping to be helpful to everyone.)

普源DS1000系列示波器labview RS232和GPIB通信驱动.(this is labview driver for Rigol DS1000.)

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.)
