Design of Digital Circuit Online Examination System

Abstract—In view of the limitations of the existing web-based examination system, a "digital circuit" online examination system was designed. This system is mainly made up of rich graphical interface in front-end development technology such as HTML5, and the asynchronous update function of Ajax technology. It not only realized online examination of special questions such as timing diagram type, karnaugh map grouping and circuit design, but also improves the operation efficiency and storage security of B/S architecture examination system.
