摘要
信号与系统是电子信息类专业学生在大学阶段的基础专业理论课。这门课主要学习如何使用科学的方法描述生活中的信息以及信号的分析和处理过程。课程内容是学生从中学阶段的被动式学习过渡到高等教育阶段的主动式学习的关键节点,包含了培养学生进行更高层次的科学理论学习和培养具备科学理论创新能力的基础理论知识。然而,在这门课的教和学的过程中一直存在很多的问题,使得很多大学生没有及时掌握这门课的内容,为后续的知识学习造成了困难。为了使学生能够快速地接受和掌握该门课程内容,文章从信号与系统课程内容特点分析和探讨这门课的一些教学思路。
Signal and system is a basic professional theory course for students majoring in electronic information at the university stage.This course focuses on how to use scientific methods to describe information in life,as well as signal analysis and processing.The curriculum content is the key node for students to transition from passive learning in middle school to active learning in higher education,which includes the basic theory knowledge of cultivating students to study scientific theory at a higher level and to cultivate the ability of scientific theory innovation.However,there have been many problems in the process of teaching and learning in this course,which makes it difficult for college students to master the content of this course in time.Knowledge learning brings difficulties.In order to enable students to accept and master the course content quickly,this paper analyzes and discusses some teaching ideas of this course from the characteristics of signal and system course content.
