Taking AM modulation and demodulation as an example,this paper introduces the teaching and research work of the experiment of combining virtual and real experiments in the course of Communication Electronic Circuits.The simulation software is convenient to observe the waveform of any node.The AM modulation and demodulation experiment is completed by Matlab and Multisim software.Students are provided with the current mainstream analog modulation chips,so that they can choose innovative topics freely,and get through the whole process of engineering practice from schematic design to hardware circuit debugging.Economical software radio equipment is introduced to complete the AM modulation system in digital mode using GNU Radio software.The related experimental process has been running for 3 years,and the teaching effect is good.
