| Abstract: | 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. |
