摘　　要：“信号与系统”是电子信息类本科阶段的专业基础课。在学习的过程中,很多同学只是记住知识点,不明白它们之间的逻辑关系,不会灵活运用。该文旨在利用思维导图的方式对系统稳定性分析方法进行总结,描述了连续时间系统和离散时间系统的稳定性,对每个系统提出了两种分析方法,即时域分析法和变换域分析法,对两种方法的具体分析过程做出了详细的说明,并对系统稳定性给出了4种判别方法。借助思维导图,帮助学生更好地理解知识,充分调动学生学习的积极性。"Signals and systems"is a professional basic course of the undergraduate level of electronic information.In the process of learning,many students just remember knowledge points,but they don't understand the logic relationship among them and cannot use them freely.This paper aims to summarize the analytical method of the system stability by mind mapping,describes the stability of the continuous-time system and the discrete-time system,puts forward two analytical methods for each system,namely the time-domain analysis method and the transform-domain analysis method,explains in detail the specific analytical process of the two methods,and also presents four discriminant methods for the system stability.With the help of mind mapping,students can better comprehend knowledge and fully mobilize their enthusiasm for learning.
