The Course Reform of Digital Signal Processing for Engineering Education

摘要

DigitaI Signal Processing (DSP) is a widely used subject in the application of engineering. However, in undergraduate teaching process, the derivation of mathematical formula and its physical meaning are outside of students' faculties of sense. For the beginners, mathematical concepts are hard for them to thoroughly understand, not to mention physical meaning and engineering concepts. Further more, this situation will directly make students lack of understanding about the essence and usages of DSP course. In the background of engineering education, it is necessary to reform the teaching method of DSP course. In view of different teaching contents and requirements, the teaching task of DSP course is completed by combining with theoretical teaching and experimental demonstration. The reform of theory teaching mainly consists of three parts: teaching contents, teaching methods and teaching form. In order to internalize knowledge and stimulate students' interest in DSP course, the engineering practice reform of experimental teaching is introduced into engineering application cases, which applies theoretical knowledge to process actual signals. The teaching reform practice results show that the teaching quality of DSP has been greatly improved. Students can process actual engineering signals after learning this course.
