“数字信号处理”和“信号与系统”两课重叠内容的处理方法探讨

Discussion of Different Teaching Methods of Overlap Content in “Signal and System” and “Digital Signal Processing”

“数字信号处理”与“信号与系统”是电子类专业非常重要的两门课程 ,由于“数字信号处理”课程内容的建立是以“信号与系统”中的概念和理论为基础的 ,因而该课程被安排在“信号与系统”之后 ,但是两门课程都有离散信号与系统方面的分析内容 ,从而造成了两课内容上的重叠 ,这就给“数字信号处理”一课中关于这部分内容的课时安排提出了问题。我们针对这个问题在连续三届本科生的教学中作了一个试验 ,本文针对这个试验及试验结果做了分析 。

Digital Signal Processing” and “Signal and System” are both fundamental courses for EE study. The contents of “Digital Signal Processing” are based on concepts and theories of “Signal and System”, so it is always arranged following “Signal and System”, but there are overlap contents in the both courses, such as analyzing of discrete signal and system, so the problem is how long time should we use on these contents in “Digital Signal Processing” teaching. To find solution, we implemented an experiment in three grades students and found the optimal time for teaching these overlap contents.
