A linear time-invariant (LTI) system is a system that satisfies both linearity and time-invariance. These characteristics apply, at least approximately, to many important systems.

In such cases, the system’s response to any given input can be found directly using convolution: where is the system’s impulse response. 1

A good example of a LTI system is any electric circuit consisting of resistors, capacitors, and inductors. 1
