<span style=\"font-size:14px;\">Signal and system is an essential knowledge base for students majoring in electronics. At present, general students have difficulties in learning signal and system courses, such as many knowledge points, close logical relationship with each other, and high requirements for mathematical foundation, which to some extent leads to the decline of learning efficiency and the deterioration of learning effect. Knowledge maps explicitly express knowledge nodes and semantic relationships among them in a structured way, which provides an effective way to sort out the interrelationships among knowledge. In view of this, this project plans to design an online learning system of signal and system based on knowledge map, and establish the knowledge base of signal and system course by using the knowledge relevance of knowledge map, which can not only manage the learning materials of each chapter effectively and reasonably, but also sort out the relevant information of each chapter quickly, which is convenient for students to study the course systematically, and make it clear at a glance what they have learned, thus greatly improving the learning efficiency.</span>
