《数字信号处理》是电子信息工程专业的一门重要专业课,是重多专业课程的基础及纽带。本文针对在实际教学中所遇到的问题,如教学内容难度大,概念抽象难理解等问题,提出了相应的教学改革方法,如教材选择、精简教学内容,注重物理意义的理解,引入MATLAB与传统教学相结合的手段等。通过实际操作,基本达到了理想目标。 “Digital Signal Processing” is an important professional course of electronic information engineering, which is the foundation and link of many specialized courses. In this paper, the problems encountered in the actual teaching, such as the difficult teaching content, conceptual abstract difficult to understand and other issues, put forward the corresponding teaching reform methods, such as teaching material selection, streamlining teaching content, pay attention to the physical meaning of the understanding, the introduction of MATLAB and Traditional teaching methods such as combining. Through the actual operation, basically reached the desired goal.
