摘　　要：采用LabVIEW7.1环境下开发的程序,组建了多功能虚拟信号发生器。该发生器不仅能产生正弦波、方波、三角波和锯齿波这4种基本波形,还可以输出其它任意波形,并可模拟实际工作环境中添加了噪声后的波形信号,同时还可轻松、快捷地将这些信号波形显示出来。解决了传统信号发生器只能产生基本波形的局限性,为学习和实践测试提供了一条捷径。Basing on LabVIEW7. 1, multi-functional virtual signal generator is built. It can not only output sine wave, square wave, triangle wave and sawtooth wave these basic waveforms, but also output arbitrary waveform. Besides, the output waves that added noise signal in the practical is simulated and showed easily and quickly. The limitation of the traditional signal generator device is solved by multi-functional virtual signal generator , which provided a shortcut for study and practical test.
