基于labview的信号发生器以及信号滤波器，功能强大，以及界面很漂亮(Signal generators and signal filter labview based and powerful, and the interface is very beautiful)

用LabVIEW编制一个完整应用软件，完成以下功能： 1、产生一个正弦波，叠加一个噪声信号，从界面上可以调整噪声和信号的幅度、频率等参数，此信号作为后续分析的信号源； 2、显示信号的时域波形，点击按钮可以显示信号的幅度谱、功率谱 3、图形上可以显示光标，具有峰值跟踪功能，同时将峰值频率、幅度显示在界面上。 4、点击按钮可以计算显示信号的失真度（THD）、信噪比（SNR）、各次谐波的频率和幅度；(Preparation of a complete application using LabVIEW software, perform the following functions: 1, generates a sine wave, the superposition of a noise signal, the interface can be adjusted from the noise and the signal amplitude, frequency and other parameters, this signal as a follow-up analysis of the signal source 2. time-domain signal waveform display, click the button to display the signal amplitude spectrum, power spectrum 3, you can display a cursor on the graph, with a peak tracking, while the peak frequency, amplitude displayed on the screen. 4, click the button to display the calculated distortion (THD) signal to noise ratio (SNR), each harmonic frequency and amplitude )

用labview实现的正态分布的随机数并生成对应的直方图(Achieved with labview normally distributed random numbers and generate the corresponding histogram)

用labview8.5实现的调用动态库例子（DLL）。用户可以参考写自己的动态库。可能需要部分组件支持，找不到的朋友可以联系我。(using labview8.5 to call dll file.)

说明：  用LabVIEW做了一个简单的菜单文件 可以实现下拉菜单选择不同的页面(Making a simple menu file with LabVIEW can realize pull-down menu to select different pages)

通过labview控制信号发生器和锁相放大器进行共振频率检测的程序。freq test.vi实现信号发生器的频率扫描，lockin test.vi 实现锁相放大器的参数设定，数据采集.vi实现锁相数据的采集，waveform arrays to file实现波形数据到文件数据的转换。共振频率测试.vi实现晶振等共振频率的测试(Resonance frequency detection procedures performed by labview control signal generator and lock-in amplifier. freq test.vi achieve frequency sweep signal generator, lockin test.vi setting parameters to achieve lock-in amplifier, a data acquisition. vi achieve phase lock data acquisition, waveform arrays to file converted waveform data to achieve document data. The resonance frequency of the test. Vi achieve crystal and other resonant frequency test)

主要运用labview的编程功能完成对信号的希尔伯特变换，从而更好的理解希尔波特变换。(The main use labview programming features to complete the signal of the Hilbert transform, so as to better understand the Hilbert transform.)

说明：  电机控制器的串口通信界面,基于labview visa,德马克电机(Serial communication interface of motor controller based on LabVIEW visa, demarcation motor)

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)

Labview制作的倒立摆仿真试验，大家可以参考一下(Labview produced inverted pendulum simulation, we can refer to)
