Sampling theorem is the important and difficult knowledge point in the course of Signal and System. How to make students understand it deeply is the key issue in the teaching proceed. In this paper, the concept of sam- piing theorem is analyzed. Through several teaching methods, i.e. the exampling method, the questioning method, the practicing method and the graphical presentation method, the content of the sampling theorem is explained, and its usage is shown.
