, MATLABMATLAB ,MATLABGUI,: MATLABGUI IIThe design of digital signal processing virtual experimentsimulation platform based on MatlabStudent:Huang Zhong-Ze Teacher: Li XinAbstract : Digital Signal Processing is the importantfoundation course of electrical and communicationsprofessionals in university, the content is very abstracty andstudents are not easy to grasp. The other hand, teachers taughtin some main contents not very convenient. Against such problemsexist in teaching,to allow teachers to teach and students tolearn. So abstract as figurative, Enhance their learninginterest. This paper represents digital signal processingvirtual experiment simulation platform using Matlab. It changesthe traditional teaching methods and focus on the content of a III platform. Operation is simple and convenient. Results is visualand accurate. Matlab provides an open environment, highlyfunctional graphical rendering. Toolbox and its features is easyto learn, which make the system development simple and fast, Thesystem uses a friendly GUI interface design, using simplelanguage, rich picture will be displayed the abstract contentin the front of the students and improved students learningenthusiasm and initiative.Key words : digital signal processing ;experimentplatform ;matlab ; .
