虚拟仪器，给予超声测距的倒车雷达的应用，用labview加以实现(Virtual instrument, given ultrasonic ranging reversing radar applications, be achieved with labview)

基于labview的频谱分析，简单的fft快速傅里叶变换(Spectrum analysis based on LabVIEW ， Simple FFT fast Fourier transform )

使用labview实现中断访问串口，使用消息队列方式传递数据。(Use labview realize interrupt visit, use the message queue serial port style to deliver data. )

基于LabvIEw的通用自动测试系统(ATs)舍计算机，可鳊程激励、响应数据采集及uuT模块，采用MxI总线控制方式。专用信号发生器为uuT提供模拟激励信号，矩阵开关和适配器完成不同信号间切换。主控计算机执行测试程序，信号发生器发送激励信号，数据采集卡采集数据，采集数据经调理后，并与标准数据|匕较是否满足相应测试结果。(The general automatic test system (ATs) based on LabvIEw can be used as a computer to excite, respond to data acquisition and uuT module. The control mode of MxI bus is adopted. Special signal generator provides analog excitation signal for uuT, matrix switch and adapter complete switching between different signals. The main control computer executes the test program, the signal generator sends the excitation signal, the data acquisition card collects the data, after the data acquisition is adjusted, and compares with the standard data | dagger whether it meets the corresponding test results.)

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 )

能够保存采集数据，保存到excle文档，以便于采集后数据保存(saving the collected data and save it to the excle document)

对LabVIEW进行二次开发，对信号进行聚合经验模态分解。(The LabVIEW is developed two times, and the signal is aggregated by empirical mode decomposition.)

分享下labview图形显示控件，非常好用的呀(Share the labview graphical display control, very easy to use, suitable for LabVIEW beginners)

说明：  查找布尔数组中的布尔为真的个数并找出所处索引位置(Find the number of Booleans and index in a Boolean array that are real)

labview中用程序去产生一个触发事件是个难点，相关的介绍和例子并不多，本程序使用值属性信号结点改变的方法去产生一个事件，实现程序控制产生触发事件的功能，labview开发版本8.2。(labview using the program to generate a trigger event is difficult, relevant examples of the introduction are not many,here we use the value change of the node attribute of the signal to generate an event, the realized the program control functions to generate trigger events, the version of labview development is 8.2 .)
