| Abstract: | 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. |
