摘　　要：“数字信号处理”是高校电子信息工程、电子信息科学与技术、通信工程等若干本科专业必修的一门专业基础课,也是接下来专业课程的基础和贯穿学科内容的纽带。为贯彻教育部提出的“四个关系”和“四个着力”,提出“以基础理论为主体”“以应用技术为牵引”和“以学科前沿问题为亮点”的三层次“数字信号处理”教学改革方法,使得“数字信号处理”课程能够被更好的学习与应用在实践中。实践结果表明,基于“三层次”思想的“数字信号处理”课程改革方法不仅有利于学生更好地吸收课堂教学内容,还有助于提高学生对水声工程专业其他相关课程学习的兴趣。Digital signal processing course is a major,professional and basic course of several undergraduate majors,such as electronic information engineering,electronic information science and technology,communication engineering,etc.It is also the basis of the following professional courses and the link through the subject content.In order to carry out the“Four Relations”and“Four Efforts”which are put forward by the Ministry of Education,this paper proposes the“three-level thoughts”teaching reform method of digital signal processing course which includes“basic theory as the main body”,“application technology as the traction”and“frontier issues as highlight”for achieving better studied and applied performance in practice.The practical result shows that the“three-level thoughts”reform method of“digital signal processing”is not only conducive to students'better absorption of classroom teaching content,but also to improve students'interest in other related courses of underwater acoustic engineering.
