Time Invariant System

If the cascade x(t)--->[time delay by t0]--->[system]---->z(t)

yields the same output as the cascade

x(t)--->[system]--->[time delay by t0]--->y(t) for any t0, then the

system is called "time invariant".


Time variant System

If the cascade x(t)--->[time delay by t0]--->[system]---->z(t)

does not yield the same output as the cascade

x(t)--->[system]--->[time delay by t0]--->y(t) for any t0, then the

system is called "time variant".
