摘　　要：本文选用LabVIEW图形化编程语言为开发软件,设计了一个用于日常教学的虚拟信号发生器。该仪器可以模拟产生正弦波、锯齿波、方波、三角波、等4种基本波形和任意的公式波形,并且各波形均可以调整其参数值的大小,其中频率范围还具有档位可调功能。该仪器所产生的波形可以以LabVIEW测试文件形式存储进行存储。This paper introduces a design method of virtual signal generator based on LabVIEW.This signal generator could be used in daily teaching.The instrument can generate and display four basic waveforms, such as sine,square,triangle,sawtooth waveform and so on.Arbitrarily formula waveform could be generated too.All of parameter values of these waveforms could be regulated. The adjusting function of frequency gear is designed too. The waveforms generated by this instrumnent could be saved as LabVIEW measurement files.
