说明：  跑马灯小程序,基于数组方式的编程，有很多方式可以实现，献丑献丑，我是新人，还请多多关照(Running horse lantern program, based on array programming, there are many ways to achieve, offering ugliness, I am a new person, but also please take care of more.)

一个简单的LABWINDOWS控制程序,实现简单的人际交互。(A simple interfaced code using Labwindows/CVI)

说明：  创建一个计时测试程序，比较公式节点和本地LabVIEW数学函数的平均执行时间。此程序需要一个For循环或一个平序或叠序结构以及一个Case结构。要求For循环运行计时测验N次，然后使用Statistics Express VI对结果做平均。要求顺序结构在代码运行之前以及代码运行之后对Tick Count进行采样。要求Case结构判定用户是要执行公式节点还是要执行本地LabVIEW数学函数。对每个分支运行计时测验程序。哪种方法执行时间最快？哪种方法最容易编程？别人要看程序时，哪种方法更容易理解？(Create a timing test program to compare the average execution time of formula nodes and local LabVIEW mathematical functions. This program needs a For loop or a plain or overlapping structure and a Case structure. Require the For cycle to run the timing test N times, and then use Statistics Express VI to average the results. The sequential structure is required to sample Tick Count before and after the code runs. The case structure is required to determine whether the user wants to execute formula nodes or local LabVIEW mathematical functions. Run the timing test program for each branch.)

在labview的信号处理中用户来计算波形的包络谱，用来进行信号分析(To calculate the wave spectrum envelope of users in the signal processing of the LabVIEW, used for signal analysis)

用于labview傅里叶变换的实用例程，可自行替换函数(A practical routine for LabVIEW Fourier transform)

利用DAQ助手实现的基于LABVIEW的示波器，可通过数据采集卡实现各种波形显示和尺度调节(Use the DAQ Assistant to achieve based on the LABVIEW the oscilloscope, data acquisition card to a variety of waveform display and adjust the scale)

LabView广泛应用于数据采集与控制、信号处理以及数据表达等方面，它提供了一种全新的编程方法，即对软件对象“虚拟仪器（VI）”进行图形化的组合操作。本课题要求编写一个基于LabView的USB数据采集系统上位机软件，其可实时对八路模拟信号进行不间断采集，实时显示和存储，可对八通道数据进行频率分析和低通滤波，并可设置采集卡的采样频率、采样点数和采样模式。采集系统所用的数据采集卡的输入信号幅度范围是-5V~+5V或0V~+5V，AD转换位数为12位，最高采样频率为1MHz，所使用的USB传输方式为高速块传输。
