摘要
根据通信原理课程理论性强而直观性弱的情况,提出了一种基于虚拟仪器技术的教学方法。介绍了虚拟仪器开发软件LabVIEW的优点和基本使用方法、与通信系统设计紧密相关的调制工具包的调用;针对通信原理实验教学,设计了一套基于虚拟仪器的总体实验方案;给出了基于调制工具包中的相关VI模块的AM和2ASK实验设计实例。与传统的通信原理课程相较,基于虚拟仪器的教学方法不仅能弥补硬件实验的不足,还更有利于激发学生的学习兴趣和创造力。
Due to the fact that communication principle is a theoretical course and weak visibility,a new teaching method is proposed based on the virtual instruments technology.Firstly,some advantages and foundations of the virtual instruments development software named LabVIEW are introduced.The key point is using LabVIEW＇ s Modulation Toolkit which is closely related to the design of communication system.Then,aiming at the experiment teaching of communication principle,an overall scheme of experiment based on virtual instrument is designed.Finally,with the support of the Modulation Toolkit,experiments including AM and 2ASK are represented.Comparing with traditional teaching method of communication principle,teaching with virtual instruments technology can not only make up for the lacking of hardware,but also stimulate students＇ interest and creativity more effectively.
