摘要
通信电子电路是通信工程、电子信息等专业学生普遍感到难学的一门专业基础课,而其中的振幅调制和解调电路又是通信电子电路中的重要电路。鉴于此,授课时在介绍其调制与解调原理基础上,以AM信号的产生与解调为例,运用Multisim 8软件环境下建立AM信号的产生和解调的电路,改变仿真电路中的相应参数,以及Multi-sim 8提供的示波器模块对产生的AM信号和相应的解调波形进行了分析。在通信电子电路课程的教学中应用Multisim 8,可直观生动地仿真该课程中的一些重要的电路,学生完全可以通过电路参数的改变和相应的仿真结果加深对课程内容的理解。
Communication electric circuit is a basic course in the discipline of communication engineering and electronic information. It is difficult for most students. Moreover, amplitude modulation and demodulation circuits are important in the course. Therefore, after the expatiating of AM （amplitude modulation） and demodulation, this paper presents the modulation and demodulation model in Multisim 8. The model uses the oscilloscope to analyze waveforms in the case of different parameters. The simulation shows that some important circuits are lively simulated with Multisim 8 software, and then applied to the teaching of the course and the students can make further understanding to those important contents through the simulations.
