The wording on the definition of a Memoryless system was good but the definition of a system with memory could be worded a little differently. For example: "depends on inputs at more than just this time" could be worded to "depends on inputs at more than that particular point in time." This helps clarify a little more. - Max Paganini
I think the definition for memoryless is excellent and agree as Max pointed out already the definition for a system with memory would be better if clarified slightly. -- Paul S.
Saying the word past time, present time and future time would have made the definition look more clear and easy to understand. more than just one time does not explains it clearly. sourabh ranka
Does "memory" apply to future input? I thought memory referred specifically to past input - Chris Cadwallader
