摘　　要：本文针对《数字电子技术》课程中序列信号发生器的设计这一教学难点问题,提出了利用EDA电子工作平台Multisim进行快速验证的教学方法,首先从理论上介绍了序列信号发生器的两种设计方案,即反馈移位型和计数型,进而以11010序列信号发生器为例详细描述了实现两种设计方案的各个步骤,在完成理论设计后即用Multisim构造电路图进行仿真验证,教学实践表明,仿真波形直观有效,此教法效果很好。该教法方便、简单、具有很强的实用性,是数字电子技术课程教学方法的一种积极探索。Aiming at the difficult teaching spot of sequence signal generator design in the course of Digital Electronics Technology,this paper proposes a new teaching method by using EDA electronic work platform Multisim to quickly verify the correctness of design scheme.First,the two design schemes for sequence signal generator,feedback shifting bit type and counting type,have been introduced theoretically.Second,each step to realize the sequence signal 11010 as a typical case by the above methods has been described particularly.Finally,the simulative electronic circuits are constructed at Multisim platform to verify its correctness after theoretical design has been finished.The teaching practice has shown that the waveforms of simulation can give visual display effectively and the proposed method can get very good results.Moreover,the method also possesses the characteristics of convenience,simplicity and high practicability.It can be concluded that the proposed method is an active teaching exploration on the course of digit electronics technology.
