应用labview实现信号的改进经验模态分解，对初学者有所帮助(Labview is applied to realize the improved empirical mode decomposition of signal, which is helpful for beginners)

开发板stm32 labview tcp/ip通讯程序，测试ok(Development board stm32 labview TCP/IP communication program, test ok)

多种调制解调的labview实现,FSK,ASK,PM,FM(A variety of modem labview implementation,FSK QPSK AM FM)

说明：  软件工程方法在LabVIEW 中的应用，对于LabVIEW编程人员，尤其是中高级编程技巧十分有用(A software engineering approach to LabVIEW programming)

模拟多种信号的产生，频率和幅值可调，并显示波形。(A variety of signals are simulated, the frequency and amplitude are adjustable, and the waveform is displayed.)

该程序基于labview2012研发，利用希尔伯特变换实现提取信号的包络。一部分是对AM信号的仿真实验，另一部分是其通用形式，只需拷贝到自己的引用程序中即可。(The program is based on the labview2012 , the use of the Hilbert transform to extract the signal envelope. Part of the AM signal simulation, another part is in its generic form, can be simply copied to the reference program.)

说明：  使用研华采集卡，labview驱动，采集数据和存储，曲线显示(Labview data acq excel save and display)

说明：  Labview虚拟示波器程序，编程入门提高(LabVIEW virtual oscilloscope program, programming to improve the entry)

labview登录模块，有注册，登录，忘记密码，修改密码的功能，数据库用的是access。(The LabVIEW login module has the functions of registration, login, forgetting password and modifying password. The database uses access.)

优点：1，PPI协议通讯速度快，比OPC ，PCAccess，Modbus 快4-5倍左右。(就这一条优点就足了，呵呵) 2，PLC端无需编写任何通讯程序。 3，可以直接对PLC进行，RUN STOP等操作。 4，本程序全部采用LABVIEW底层程序框图，没用调用任何的DLL ，API等。这点对你学习还是修改程序功能都很有帮助，方便。 (Advantages: 1, PPI protocol communications faster than OPC, PCAccess, Modbus about 4-5 times faster. (On which an advantage on the feet, huh, huh) 2, PLC-side without writing any communication program. 3, can be carried out directly on the PLC, RUN STOP operation. 4, the procedure used in all LABVIEW underlying the block diagram, useless to call any DLL, API, etc. This is for you to learn or modify the program features are very helpful and convenient.)
