Time-invariant System
A time-invariant (TIV) system is one whose output does not depend explicitly on time.
- If the input signal produces an output then any time shifted input, results in a time-shifted output
This property can be satisfied if the transfer function of the system is not a function of time except expressed by the input and output. This property can also be stated in another way in terms of a schematic
- If a system is time-invariant then the system block is commutative with an arbitrary delay.

Famous quotes containing the word system:
“For the universe has three children, born at one time, which reappear, under different names, in every system of thought, whether they be called cause, operation, and effect; or, more poetically, Jove, Pluto, Neptune; or, theologically, the Father, the Spirit, and the Son; but which we will call here, the Knower, the Doer, and the Sayer. These stand respectively for the love of truth, for the love of good, and for the love of beauty.”
—Ralph Waldo Emerson (1803–1882)
