摘　　要：针对数字电路技术课程教学现状和存在的问题,运用LabVIEW开发平台开发出一套用于数字电路技术教学中的虚拟演示实验系统,并以数值比较器和RS触发器这两个虚拟演示实验为例加以介绍。教师可以在教学过程中动态地演示出信号参数的变化对实验现象的影响。实际应用表明,LabVIEW应用于数字电路技术课程教学中,既丰富了教学手段和教学方法,又增强了学生学习的积极性和兴趣。虚拟仪器设计实践应用于理论教学中,开拓了一个全新的教学平台,有助于提高学生的综合素质。In view of the digital circuit s problems in learning and teaching,a set of virtual demonstration experiment system for digital circuit teaching is designed based on LabVIEW programming environment,and two virtual demonstration experiments which are value comparator and RS trigger are introduced.Teacher could dynamically demonstrate that the variable signal parameters had an effect on experiment phenomenon in these teaching programs.Practical application showed that the application of LabVIEW in the digital circuit teaching had greatly diversified the teaching methods and means,strengthened the interest and initiative of students study.Virtual instrument design is used in the course of theoretic teaching to develop a new teaching platform,which helps to improve students comprehensive quality.
