| Abstract: | The experimental teaching of the sampling theorem is more important as it is a major theorem in digital signal processing. This paper designs a experimental teaching of sampling theorem based on the MATLAB characters, such as effective data calculation and symbol calculation, perfect figure processing function, visible results of calculation and programs, friendly interface of users and natural language close to mathematics formula. A satisfactory result has been gained by means of programming and simulation. |
