Abstract: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 sampling 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.It is helpful for the students to understand and apply the sampling theorem.These methods get an excellent result in teaching program
Keywords:signal and system  sampling theorem  teaching method
