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.
