“通信电子线路”课程中集成电路的仿真与教学

Simulation of Integrated Circuit Based on Multisim in Communication Circuit Assistant Teaching

本文提出采用Multisim来仿真"通信电子线路"课程中的集成电路,结合MC1596芯片作为乘法器的部分应用功能,完成了幅度调制和解调、载波提取等仿真。在课堂上利用多媒体教学显示其具体电路的实现、中间过程及输出结果,可以加深学生对"通信电子线路"课程中难懂内容的理解,并能拓展学生的视野,提高教学效率与质量。

This paper proposes using Multisim to simulate integrate circuit in Communication Circuit course teaching. The circuit board of AM modulation, demodulation and carrier extracting is designed by MC1596 IC, in which process and indication is showed in Multisim. Due to apply Multisim in multimedia teaching, the principle content and integrated application of the course becomes vivid reappearance. Visual aid demonstration circuit is enhanced. It makes students to study communication circuit more easy.
