point -When we take up design of systems, ideally how do we define the stability of a system?* A system is unstable, if a bounded input gives a bounded output, for all values of the input A system is unstable, if a bounded input O gives a bounded output, for some values of the input A system is stable, if a bounded input O gives a bounded output, for some values of the input A system is stable, if a bounded input O gives a bounded output, for all values of the input
