Design and Implementation of Digital Circuit of Multi Level Experimental System Based on LabVIEW

In order to meet the need of modern experimental teaching, improve experiment of openness and flexibility. Constructing digital circuit experiment system, fully embodies the virtual instruments in experimental operation of the advantage based on the virtual instrument technology, LabVIEW. Through the analysis of digital circuit experiment in actual effect of virtual instrument technology, shows the digital experiment system more simple and convenient, and some characteristics of relative stability and performance and experiments small errors and use convenient and save costs etc,so can be widely used in experiment teaching. Not only expanded experiment scope and space, but also can exert students' initiative and creativity.
