Case-based teaching is conducive to addressing the issues of the abstract mathematical theories in the "Signals and Systems" course and the difficulties students face in understanding and applying them. However, how to design teaching cases with major’s traits remains a question that needs continuous exploration. To this end, this paper, through an analysis of the characteristics of the electronic science and technology major at our institution and the positioning of the "Signals and Systems" course in this major, takes the phase frequency characteristics of signal distortion-free transmission as an example, designs a teaching case based on integrated optical waveguide for its physical implementation, and then explores the ideological and political elements contained therein. The outcomes can build a bridge for students from the analysis theory of signals and systems to the characteristic practice of semiconductor integrated circuits, thereby helping to enhance the effectiveness of classroom teaching and improve students ability to connect theory with practice.
