信号与线性系统是电子、通信类专业必修的专业基础课,它主要研究线性非时变系统的基本理论和基本分析方法,通过学习进一步培养学生的思维推理能力和分析计算能力,并为进一步学习通信、控制等后续专业课程奠定必要的基础。但由于学生的基础差距较大,而本课程涉及内容较多,且比较抽象,计算量大,技巧性很强。以数学方法为主要分析工具的教学过程往往难以调动一些学生的学习积极性,从而直接影响其学习效果。如何提高这门课程的教学效果.是一个值得探讨的问题。
The signal and linear system is a compulsory professional basic course for electronics and communication major. It mainly studies the basic theory and basic analysis methods of linear time-invariant system, further cultivates students’ thinking reasoning ability and analysis and calculation ability through learning, and further studies communication , Control and other follow-up professional courses to lay the necessary foundation. However, due to the large gap between students’ fundamentals, this course involves more content, more abstractness, more computation and more skill. The teaching process based on mathematical method as the main analysis tool often can not mobilize the enthusiasm of some students and thus directly affects the learning effect. How to improve the teaching effect of this course is a question worth exploring.
