hey,your definitions are very good.It not only defines ,but also explains through your examples.Even my concept of stable system is quite cleared after going through your definition.-ananya
Two issues with the definition of a stable system. It should be worded as "A system is therefore said to be bounded if any bounded input yields a bounded output". The words output/input were switched, and the definition must be stated for any input, as all possible bounded inputs must yield a bounded output (otherwise it is unbounded). -- Jeff Kubascik
