摘要
针对"数字信号处理"课程存在实践环节薄弱等问题,研制"口袋实验室"开展理论和实践一体化教学.设备以软硬件开源的Wemos D1 mini单片机为核心,以人体心电脉搏信号研究对象,采用模块化设计思想,具有性价比高、可扩展性强、便携性好等优点.同时,重构知识体系及教学内容,开发教学资源,开展理实一体化教学改革与实践.教学实践结果表明学生的数字信号处理能力得到有效提升,教学效果良好.
Abstract
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.
