说明： 传统的波形发生器采用模拟技术的方法，这种方法构成的波形发生器电路结构复杂，仅能产生正弦波、方波、锯齿波和三角波等几种简单波形。而现在在高科技领域，我们需要的可能是一些任意波形，如在保密雷达发波等军事方面和地震波形、汽车碰撞波形等模拟仿真应用方面。任意波形发生器现在被广泛用于自动控制系统、振动激励、仪器仪表领域。我国目前在这方面还比较落后，特别是在用DDS技术实现任意波形发生器方面。本课题我们打算用DDS技术基于FPGA核心板设计一个任意波形发生器。该仪器我们用LabVIEW来写的控制面板实现与FPGA的通信，实现任意波形数据的采集，并具有良好的人机交互界面。用液晶显示屏显示波形的幅度和频率。用4×4键盘控制相关波形的输出。用AD和低通滤波电路实现数电到模电的转换(The traditional waveform generator adopts the method of simulation technology, this kind of method constitute the waveform generator circuit structure is complex, can only produce sine and square-wave, sawtooth wave and triangular several simple waveform. And now in the high-tech fields, we may need some arbitrary waveform is, as in LeiDaFa confidential military aspects and seismic waves, automobile collisions wave wave simulation application. Arbitrary waveform generator is now widely used in automatic control system, vibration, instruments field. At present in this respect, especially in still lag behind with arbitrary waveform generator DDS technology. This task we intend to use DDS technology based on FPGA core board design an arbitrary waveform generator. The instrument to write with LabVIEW, we realize the control panel and FPGA communication, realizing arbitrary waveform data acquisition, and has good human-machine interface. With LCD display wave amplitude and frequency. Use 4 )

跑马灯
跑马灯是一种电脑编程工具，利用涂鸦等效果显示文字。电脑中的跑马灯，跑马灯在编程中，通常指有时需要用一矩形条显示少量用户特别关心的信息，这条信息串首尾相连，向一个方向循环滚动。(The marquee is a computer programming tool that uses text such as graffiti to display text. In the computer, the marquee and the marquee are usually programmed to display a small amount of information that the user is particularly concerned with. This string of information is connected end to end and scrolls in one direction.)
