摘　　要：LTI系统时域分析以微积分学为分析工具,纷繁复杂的知识点与大量的数学计算常常让众多学生望而却步。通过一张知识构图从知识的广度和深度上涵盖主要内容,并引入了问题追溯法、动图分析法与对比分析法来解决教学难点,使得学生的学习有迹可循,并激发其学习兴趣,拓展其学习思维。The time domain analysis of LTI system takes calculus as the analysis tool.The complicated knowledge points and widely used mathematical calculation often make many students lose interest.This paper tries to cover the main knowledge widely and deeply with one knowledge map,and introduces the problem tracing,moving diagram analysis and comparative analysis methods to solve the teaching difficulties,so that students’learning can be followed.It is also expected to stimulate their learning interest and extend their thinking ways.

关 键 词：信号与系统 LTI系统 时域分析
