In this video, Professor Emil Björnson explains what a linear time-invariant (LTI) system is, and how such systems interact with signals. In particular, examples of linear and non-linear are provided, as well as examples of time-invariance and time-varying systems. These concepts underpin the study of communication systems, where the communication channel is a system.
