《数字信号处理》课程“三度”案例式教学方法

“Three-Degree” Case Teaching Method in “Digital Signal Processing”

摘要: 为了提高学生的实践能力和创新能力，文章提出《数字信号处理》课程“三度”案例式教学方法，即选取的教学案例有温度、有热度、有深度，也就是将经典的理s论知识与教师科研、前沿技术以及中国贡献相结合。以“FIR数字滤波器”知识点为例进行了具体的介绍。“FIR数字滤波器”的教学案例包括导入案例、拓展案例、应用案例以及信息技术创新案例。丰富的案例从不同的角度拓展和延伸了FIR数字滤波器知识点，使学生在掌握基本知识的同时，锻炼了实践能力、创新能力、分析和解决实际问题的能力；丰富了知识面，培养了信息素养；更重要的是增强民族自信，有致力科技兴国的决心。对于《数字信号处理》课程的教学改革具有一定的参考价值。

Abstract: In order to improve students’ practical and innovative abilities, a three-degree case teaching method for “Digital Signal Processing” course is proposed in this paper, which selects cases with temperature, heat, and depth. The method is combining classic theoretical knowledge with teachers’ researches, brand-new technologies, and Chinese contributions. A specific introduction is given selecting “FIR digital filter” as an example. The teaching cases of FIR digital filter include introduction cases, expansion cases, application cases, and information technology innovation cases. The rich cases expand and extend the knowledge of FIR digital filter from different perspectives, enabling students to master basic knowledge, exercise practical, innovative, analytical and solving problems abilities. Students enrich knowledge and cultivate information literacy. More importantly enhance national confidence and have the determination to contribute to the development of science and technology for the country. This has certain reference value for the teaching reform of “Digital Signal Processing” course.
