When you see a system with LTI inside of it, it stands for Linear Time Invariant.  It is easy to test to determine if a system is LTI or not.  You simply put a function through a delay (z^-1) and then through the system.  Next, you put the same signal through the system and THEN through the delay.  If the outputs are identical then the system is LTI.
