基于LabVIEW的虚拟数字电路实验系统的设计 摘 要 当今社会在校学生人数急剧增加，传统的实验仪器已不能满足实验需要，学生的实际实验训练得不到满足，尤其是理工科学生，没有实验训练，抽象的理论知识很难理解。随着低成本高性能的计算机资源普及运用，数字化仪器平台逐渐取代传统电子仪器已成为一种趋势。如果把虚拟仪器运用到实验教学和科研中，不但可以节约大量仪器设备的需要，也提高了实验教学和科研的效率和质量。数字电路作为电子信息类各专业的主要技术基础课程之一，其实践实验环节尤为重要。用虚拟仪器技术构建数字电路实验系统，将广泛的应用到实验教学中。 关键词：虚拟仪器技术，数字电路，实验系统，LabVIEW ABSTRACT In todays society, the number of students increased exponentially, The traditional experimental apparatus has been unable to meet the need of experiment, Students do not meet the actual experiment training, Especially for students of science and Engineering, No experimental training, Abstract theory is hard to understand.With low cost and high performance computer resources use, Digital instrument platform gradually replaced the traditional electronic instrument has become a trend. If the virtual instrument used in the experiment teaching and scientific research, Not only can save a large amount of equipment needs, but also improve the experimental teaching and the scientific research quality and efficiency. Digital circuit for electronic information majors mainly technical basic course of, The experimental practice link is particularly important. Using the virtual instrument technology to construct digital circuit experiment system, will be widely applied in the experimental teaching.
