-A time invariant system is a system for which when a signal passes through a system and then is time shifted, it is equal to when the signal is time shifted and then passed through the system.
-For Example:
-System --> sqrt[of signal]  =  Time invariant
-In other words,
-X(t) is input signal
-X(t) --> system --> y(t) = sqrt[X(t)]  --> delay --> z(t) = sqrt[X(t - t0)]
-is equivalent to
-X(t) --> delay --> Y(t) = X(t - t0)  --> system --> z(t) = sqrt[X(t - t0)]
-Therefore it is Time invariant.
--Note: if i am wrong about this example, let me know.  Thanks.
