Web-based interactive virtual laboratory system for digital circuit experiment

Abstract

With the development of E-learning technology, web-based virtual laboratory has aroused more and more attention of educators. In this paper, we describe the design of a web-based electronic circuit virtual laboratory system for digital circuit. This system provides the user with real expression, convenient operation and powerful simulation capability. Furthermore, we designed segment-simulation mechanism and circuit status persistence mechanism to realize the simulation process in digital circuit. At the moment, ECVlab (Electronic Circuit Virtual Laboratory) has been implemented and successfully applied in an undergraduate course in Zhejiang University and has gained positive evaluation from the undergraduate students. © 2007 Springer.
