摘　　要：目前,工科高校在进行数字信号处理课程实验教学的过程中,基本都采用Matlab,Labview等软件仿真的方式,该方法能够帮助学生验证课堂所学理论知识,但直观性不强,难以帮助学生建立完整的应用设计思路和概念。针对该问题,提出基于综合性实验的数字信号处理课程实践型教学方法,并设计语音信号采集和处理系统作为实验载体;同时,完成面向硬件实践的实验课程设计,帮助学生理解数字信号处理过程的细节,掌握硬件设计方法,为后续课程学习打下良好的基础。At present,the experimental course for digital signal processing in engineering university is implemented by simulation software,such as Matlab,LabView and so on.The simulation experiment can help students understand knowledge in class more precisely.However,this kind of method lacks explicitness and cannot help to build complete application design idea and concept.In order to solve this problem,a kind of practical teaching method for DSP course based on comprehensive experiments is proposed,and an audio signal acquisition and processing system is designed.Besides,the experiment course based on hardware practical application is also designed,and it can help the student to understand the signal procedure in detail,learn hardware design method,so that the preparation for later course can be established.
