The SIMULINK simulation technique is applied to the class teaching of digital signal processing in this paper

so that the equation complexity and theory Abstraction of the course can be overcome to a certain extent.The teaching method based on the SIMULINK technique can directly demonstrate the Abstract theory in the forms of vision and hearing

which helps the students understand the complex theory on the base of intuitive recognition and therefore promotes the conventional theory teaching.At the same time

the students can study the digital signal processing from the angle of engineering application

and a subtle influence can be exerted in their engineering attainments.Based on the above teaching mode

the class teaching quality can be effectively improved

and the initiative and creativity of the students can be cultivated simultaneously.
