labview数字调制解调

说明：  NI Style control group, which contains some style controls other than the self-contained controls, can beautify the interface style.

如何制作LabView控件，赖卫国整理，方便可行(How to make labview control, Lai Weiguo collation, convenient and feasible)

简单虚拟示波器，能调节幅值，频率，相位和偏移量四种变量。(Simple virtual oscilloscope can adjust four variables: amplitude, frequency, phase and offset.)

对于无法实现硬件定时的数据卡来说，这个vi提供了软件定时的功能(For data cards that cannot achieve hardware timing, this VI provides software timing capabilities)

摘要：以实际工程为背景，介绍了在I丑bwindows／CVI环境下，基于ActiveX技术访问Microsoft Excel 2003的方法，以及创建 自动化仪器驱动器的方法。详细阐述了访问Excel具体函数的使用方法，实现了对Excel的访问。通过该工程实例，说明 了本方法具有重要的工程实用价值。(Abstract：The approach of accessing to Microsoft Excel 2003 based on ActiveX technology in LabWindows／CVI environment is intrt~ uced，in 8cN~ence，the establishments of driving scheme for automatic instruments are presented in detail．To realize the access to Excel，the operations of accessing to the real functions are intensively illustrated as wel1．Th e experiments in the real environment demonstrate that this method illustrated here is of great value for practical applications．)

labview中实现前面板的打印，打印格式为PDF.通过设置VI的属性实现报表打印(achieve labview front panel printing, print format is PDF. realized by setting the properties of print statements VI)

labview 双通道信号采集和回放系统，可以实现信号采集，设置频率(labview dual-channel signal acquisition and playback system that can achieve signal acquisition, set the frequency)

本问使用labview进行信号分析，主要用到了傅立叶变换和小波分析，感兴趣的可以看看，就是全英文的，不好看懂(The Q signal analysis using labview to the main use of the Fourier transform and wavelet analysis, may be of interest to look at, that is, in English, and good read)

说明：  读取TDMS文件，labview 2016 测试通过。(Read the TDMS file, and LabVIEW 2016 passed the test.)

实现labview的串口通讯，控制下位机两路继电器，以及控制电机旋转。(Achieve labview serial communication, the next crew to control two relays, as well as to control the motor rotation.)
