《Labview高级编程与虚拟仪器工程应用》第10章，关于液压系统测试的源码。包括： 1.“溢流阀动态”测试程序，其中小波变换使用了光盘中提供的VI,来自NI公司的高级信号处理工具包6.1版。“溢流阀动态.vi”是主程序。 2.“液压教学实验台”，“液压测试系统.vi”是主程序。 3.“机油泵”试验程序需要较多外部硬件支持。其中的dll用于国内某一特定品牌扭矩仪。“程序”文件夹的“main.vi”是主程序。 4.“转向泵”试验程序需要外部硬件支持。“程序”文件夹的“转向泵试验.vi”是主程序。(Labview high-level programming and virtual instrument engineering application)

labview中usb raw设备的读取和写入程序 非常有用(labview usb raw device in the read and write process is very useful)

本文通过运用myDAQ搭建一个在线音效处理系统，利用LabVIEW控制myDAQ完成信号的采集、分析以及发生。 (By using myDAQ build an online audio processing system, using the LabVIEW Control myDAQ complete signal acquisition, analysis, and happen.)

有关labview 的串口通信，实时显示数据，并且进行后台保存，输出文件(about labview serial com interfce communication ,diaplay data timely and save it behind )

说明：  事件状态机(Event state machine)

用户自行输入所需要的频率和占空比，得到PWM波(Users input the required frequency and duty cycle to get the PWM wave.)

基于Labview的编程，能够显示物体在三维空间中的具体方位和姿态.(Display the acceleration and orientation of the object based on Labview.)

说明：  本Demo演示了NI公司LabVIEW图形化开发环境的并行编程模式。在并行循环之间可以通过队列或者是局部变量传递数据。(This Demo demonstrates the parallel programming model of NI's LabVIEW graphical development environment. Between parallel loops, data can be passed through queues or local variables.)

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

航空航天通信技术一般采用模拟通信的频率调制和数字通信的移相键控调制方法。这有利于充分应用信道带宽和能源。频率调制是在一定程度上改变载波或副载波的频率来传输信息的调制方法。移相键控调制是利用载波或副载波的相位跳变来传输信息的调制方法。移相键控又分二相移相键控、四相移相键控和多相移相键控，其中以四相移相键控和八相移相键控调制方法的效率较高(Aerospace communications technology commonly used analog communication of frequency modulation and the digital communication phase shift keying modulation method. This is helpful for making full use of channel bandwidth and energy. Frequency modulation is changed to some extent carrier or subcarrier frequency to transmit information modulation method. Phase shift keying modulation is the use of carrier or subcarrier phase jump to transmit information modulation method. Phase shift keying and binary phase shift keying, four phase shift keying and multiple phase shift keying, of which four phase shift keying and eight phase shift keying modulation method of high efficiency )
