摘　　要：传统的信号发生器只能产生正弦波、方波、三角波和锯齿波4种基本波形,而且体积庞大、接口不灵活、系统封闭、价格昂贵,针对这些缺点,本课题设计开发了一套基于虚拟仪器技术的信号的产生及数据处理系统,包括信号频谱分析及滤波。文中详细介绍了基于LabVIEW的信号处理系统的组建方法,重点阐述了用户界面及应用程序的设计。In contrast to the traditional signal generator which can only output the sine wave,the square wave,the triangle wave and the saw-tooth wave,which also has disadvantages of large volume,inflexible interface,closed system and high price,this paper designes a virtual instrument including function generator and fiter based on LabVIEW, which can not only have the basic profiles,but also offers three different kinds of filters.
