labview数据采集和处理系统例子，能够对初学者有一定的帮助和学习借鉴(LabVIEW data acquisition and processing system examples, can be helpful for beginners and learn from)

labveiw实现基带信号的幅度调制（AM），频率调制(FM)和相位调制(PM)，可以在波形图中看到调制信号和调制后信号的叠加和对比，可以看到频域波形。载波与基带幅度和频率参数均可改变。(Baseband AM/FM/PM in labview. In the vi, you ll be able to see the modulated signal in both time and frequency domain.)

通过输入用户名和密码后登录，实现输入正确和错误提示、登录前禁用并灰显读取按钮、登录后启用读取按钮、读取并显示文本文件内容、加密程序框图查看操作。(By inputting user name and password and login, we can input correct and error prompts, disable and gray display the reading button before login, enable the reading button after login, read and display the contents of text files, and view the encrypted program block diagram.)

通过labview程序的演示，进一步掌握生产者与消费者循环，该压缩文件中包含有如何控制箱子的移动，及方向的控制等(Through the LabVIEW program demonstration, further grasp the producers and consumers of circulation, the compressed file contains how to control the moving direction of the box, and control)

CCD相机控制程序，用labview 驱动线阵CCD，可以设置采样时间/频率/曝光度等参数。(CCD driver,drive CCD camra with labview, with controlling of sample time parameter.)

在labview中取字符串的低八位 操作简单(Take the low eight bits of the string in LabVIEW)

labview串口接收、发送（分开）程序以及总通信程序(LabVIEW serial port receive, send (separate) program and general communication program)

给出百分制成绩，要求输出成绩等级，90分及以上为A，80分至89分为B，70分至79分为C，60至69分为D，59分及以下为E，小于0分或者高于100分弹出错误提示框。(Given percentile scores, the required output Grade, 90 points and above for A, 80 to 89 are divided into B divided into C, 70 to 79, 60 to 69 is divided into D 59 and for E < 0 or higher than 100 pop-up error message box.)

锁相技术在测控、通信、数字信号处理等众多领域得到了广泛的应用。虚拟锁相环成为锁相环发展趋势之一，根据锁相环路的基本组成及原理，利用LabVIEW软件提供的强大的数值计算和信号分析等能力对锁相环进行设计。实验和仿真结果表明该软件锁相环具有较好的捕获和跟踪性能。利用软件实现的锁相环比硬件锁相环具有更好的灵活性和通用性，同时具有结构简单、参数设计灵活等优点。(Lock-in technique in many areas of monitoring and control, communications, digital signal processing, has been widely used. Became one of the virtual phase-locked loop phase-locked loop trends, according to the basic principles of composition and phase-locked loop, using LabVIEW software provides powerful numerical calculation and signal analysis capabilities such as phase-locked loop design. Experimental and simulation results show that the software PLL has a better acquisition and tracking performance. Use of software than hardware locked loop PLL has better flexibility and versatility, but also has a simple structure, flexible design parameters, etc..)

本vi用于计算给定一维数组的艾伦方差及傅里叶变换。用于数据分析。(This VI is used to compute the Alan variance and Fourier transform of a given one-dimensional array. For data analysis.)
