摘　　要：针对数字电路课程教学的现状和存在的问题,结合虚拟仪器技术,利用LabVIEW开发平台设计出一套用于数字电路课堂教学中的虚拟演示实验系统,并以同步二进制计数器虚拟演示实验为例加以介绍。教师可以在教学环节中动态地演示出信号参数的改变对实验现象的影响。该实验系统是教师教学的演示工具、学生自学能力提高的助手和导师。结论经过实践表明:该系统开发周期短,成本低,同时又具有很强的兼容性和扩展性,易于升级换代和维护。In view of the present situation and existing problems ofdigital circuit course teaching, combining with virtual instrument technology, a virtual demonstration experiment system for digital circuit classroom teaching is designed by using LabVIEW development platform , and the virtual demonstration experiment of synchronous binary counter is introduced as an example. Teachers can dynamically demonstrate the effect of signal parameter changes on experimental phenomena in the teaching process. The experimental system is a demonstration tool for teachers＇ teaching, and an assistant and a tutor for improvingstudents＇ self-learning ability. ConclusionThe practice shows that the system has a short development cycle, low cost, strong compatibility and expansibility, and is easy to upgrade and maintain.
