摘要
在“信号与系统”课程中,时不变性是系统的重要性质。根据笔者的教学体会,将系统的输入输出解析关系抽象为三类函数,并且分析了这些系统的时不变性,从而使学生能够快速有效地判别系统的时不变性。
The time-invariance is a crucial property of systems in the course of Signals and Systems. In this paper, based on the author＇s experience of lecturing, the analytical relationships between output and input of the systems have been abstracted as three functions, on which the time-invariance of these systems have been analyzed based. Therefore, based on these functions, the students can judge the time-invariance of systems easily.
