| Abstract: | Aimed at the profound theories and abstract concepts of communication principle curriculum,the graphics of Matlab and the system simulation are applied to the simulation experiment of communication systems,and an experiment teaching system of analog signal transmission based on the Matlab simulation platform is proposed according to the principle of analog modulation and demodulation.The purpose is to verify the transmission process of analog signal with examples. The students create the simulation process of the signal transmission based on the Matlab by themselves and the waveform and spectrum characteristics of each point can be real- time displayed,which can make the classroom knowledge combined with the debugging software system effectively,deepen students＇ understanding of knowledge and promotes the students＇ ability and innovation spirit. |
