将波形数据写入文件，然后读取出来显示波形

基于Labview的数字滤波器与频谱分析仪 滤波器可以选择是否打开滤波器，可显示波形，可设置滤波器参数，可测量时域、频域的参数，可保存数据、图像；频谱分析仪可显示波形，可测量频域参数(Labview-based digital filter and spectrum analyzer filter can choose whether to open the filter to display the waveform, the filter parameters can be set to measure the time domain, frequency domain parameters, save the data, images spectrum analyzer display waveform, measurable frequency domain parameters)

说明：  工业显示屏用于生产现场数据的显示与记录. 有与数据库交互与S7交互的操作.(Industrial display screen is used to display and record data of production site There are interactive operations with database and S7)

说明：  使用LABview2018制作的串口调试助手，支持十六进制、文件发送等功能。(The serial port debugging assistant made by labview2018 supports functions such as hex and file sending.)

通过输入域名，打开默认浏览器加载网页，实现第三方加载。(open web)

神经网络在数据处理或模式识别中具有重要作用，这里采用LabVIEW实现了神经网络的功能，供工程师使用。(Neural networks play an important role in data processing or pattern recognition. LabVIEW is used here to implement the functions of neural networks for engineers to use.)

Labview 实现调用动态链接库 有详细说明 程序案例和与案例说明 是学习的好材料！(Labview implementation calls the dynamic link library procedures are described in detail with examples and case notes are a good learning materials!)

Labview的小波分解与还原程序，没有调用matlab，配套论文，可以此为基础改成小波去噪程序(Labview wavelet decomposition and reduction program, there is no call matlab, supporting the thesis, this can be changed based on wavelet denoising procedure)

基于LabVIEW的标定训练原始图片与演示程序(Calibration Training and Demonstration Program)

这是一个QPSK的调制及解调过程的例子，供大家学习参考(This is the example of a QPSK modulation and demodulation process for them to learn from the reference)

说明：  利用labview实现登录和修改密码（账号密码在txt文本文件中）(To sign in and change password)
