Knowledge Graph Empowers the Construction of "Signals and Systems" Course and Its Digital Teaching Reform and Practice

This paper explores the application of knowledge graphs in the construction of the "Signals and Systems" course and its digital teaching reform and practice. By integrating knowledge graphs, the course content is made more structured and accessible, enhancing students' learning experience and teaching effectiveness. The study shows that knowledge graphs can effectively organize and present complex information, making it easier for students to understand and apply. This approach not only improves the quality of teaching but also promotes students' active learning and problem-solving abilities.
