摘　　要：在通信原理课程的教学中,学生常常因课程理论性强、概念抽象而不易理解和掌握,失去了学习的兴趣。文章详细论述了基于LabVIEW的DSB信号调制与解调的仿真过程,实现了系统输入输出波形的直观显示,动态展现了模拟调制系统的时域波形与频域频谱的关系。教学实践表明:运用LabVIEW仿真软件可以使抽象概念具体形象化,加深了学生对基本原理的理解,极大地调动了学生的积极性,提升了课堂教学效果。In the teaching of communication principle course,students often lose their interest in learning because of the strong theoretical nature and abstract concepts of the course.This paper discusses in detail the simulation process of DSB signal modulation and demodulation based on LabVIEW,realizes the intuitive display of system input and output waveforms,and dynamically displays the relationship between time-domain waveform and frequency-domain spectrum of analog modulation system.Teaching practice has proved that the use of LabVIEW simulation software can visualize abstract concepts,deepen students'understanding of basic principles,greatly mobilize students'enthusiasm,and improve classroom teaching effects.
