Your definition is very clear.I didnt find any faults in it.

You have given an excellent definition of a memoryless system, but you also need to give a defintion of a system with memory.

Your definitions are solid along with your examples. You lay things out so they are easily understood. - Joseph Mazzei
You did a good job of explaining the definition in words and followed it up with good examples and descriptions. Nice work. David Record
You explanation of memoryless system was very understandable and the examples made the concept even clearer. -- Aishwar Sabesan
Nice example of a memoryless system with a (t-1) term. I think such examples help prove the point that one cannot simply look for a (t-1) in the system's equation and immediately conclude that the system is memoryless.
