Design and Teaching Practice of"Pocket Laboratory"for Digital Signal Processing Course
Aiming at the problems of weak practical links in the existing teaching mode of Digital Signal Processing course,a"pocket laboratory"was developed for the integrated teaching of course theory and practice.The device is developed based on the open source Wemos D1 mini single-chip microcomputer of software and hardware,the human's ECG and pulse signals are employed as the research objects.It adopts the modular design idea,and has the advantages of high cost-effectiveness,strong scalability,portability and so on.Meanwhile,the knowledge system and teaching content are reconstructed,and the teaching resources is developed.The"pocket laboratory"is utilized in teaching and practice reform.The results of teaching practice show that students'digital signal processing ability is effectively improved,and the teaching effect is better.
