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

You must have fixed what jeff was complaining about, because when I read it it was correct.  Good Job.

I think you should clarify your first sentence:
 +
"An input is said to be bounded if it is bounded above and below for all values of t."
 +
What is "it" referring to? By this, it sounds like a bounded input determines a stable system which conflicts with the latter half of your definition. - Chris Cadwallader

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
