摘　　要：以AM调制解调为例介绍了“通信电子线路”课程虚实结合实验的教学研究工作。采用虚拟仿真实验可便于观察任意节点的波形,AM调制解调实验采用Matlab和Multisim软件完成虚拟仿真内容。提供当前主流的模拟调制芯片给学生,让其自由地创新性选题,打通从原理图设计到硬件电路调试的工程实践全流程。最后引入经济型软件无线电设备,使用GNU Radio软件在数字模式下完成AM调制系统。相关实验流程运行3年,教学效果良好。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.
