A Linear Time-Invariant (LTI) system is a mathematical model that describes a specific type of dynamic system in the fields of engineering and signal processing. An LTI system is characterized by two main properties: linearity and time invariance. \#\#\# 1. Linearity: A system is linear if it satisfies the principles of superposition.
