Abstract

Sound card-based virtual instrument technology, through the program processing of the collected data by sound card under LabVIEW environment, this paper designed a low-cost virtual oscilloscope system. The design has advantages of user-friendly interface, high flexible, high performance-price ratio and the others. The experiment simulation shows that the system can correctly collect sound card signals and achieve oscilloscope´s measurement and frequency spectrum analysis function. It is conducive to university teaching in the new situation.
