Another common of LTI full form is Linear Time-Invariant, a term used in mathematics, engineering, and signal processing to describe a system that satisfies two properties: linearity and time-invariance. A linear system is one that follows the principle of superposition, which means that the output of the system is proportional to the input.

A time-invariant system is one that does not change over time, which means that the output of the system depends only on the current input, not on the past or future inputs. For example, if you shift the input by a certain amount of time, the output will also shift by the same amount of time.
