Design of Virtual Signal Generator Based on LabVIEW9.0

Rong Xiang-xiang

Abstract

It introduces briefly the concept and characteristics of virtual instrument technology and LabVIEW,focuses on the design of virtual signal generator system using virtual instrument technology and LabVIEW9.0 combining the functions of common signal generator.The system can output common function waveform such as sine wave,triangle wave,square ware and saw tooth wave,it also can output formula wave using formula option and output noise waveform.The virtual signal generator has a friendly interface.It can perform to complete the appropriate signal processing requirements and output waveform by operating the buttons on the front panel.This system has easy operation,can be widely applied in teaching and research fields.
