数字信号处理是电子信息工程专业的核心课程,其理论性强,应用领域广泛。但课程公式繁多、枯燥难学、内容多、知识点分散,导致大多数学生学习起来较为困难,从而引发学生对课程的学习兴趣不浓等问题出现。作者根据教学时所积累的经验,针对产生问题的主要原因,从课程的知识结构、实验教学、教学模式等方面进行了改革与探讨。 Digital signal processing is the core course of electronic information engineering, its theory is strong, a wide range of applications. However, the formula of the course is numerous, boring and difficult to learn, with many contents and scattered knowledge points, which makes most students find it more difficult to learn, which leads to students’ lack of interest in the course. According to the accumulated experience in teaching, the author aimed at the main reasons for the problem and carried out the reform and discussion from the aspects of knowledge structure, experimental teaching and teaching mode.
