Just amazing. Pretty simple, too. Thanks

Unfortunately, impulse signal tends to infinity as t tends to zero. Therefore, it's not a bounded input, since the requirement for a bounded input is to have finite value at each and every instant of time. Instead, unit step input could be an example of bounded input.

Isn't the rule that the ROC must include the imaginary axis? For this to be true the system must also be causal to be stable? Agree?

if real number is negative it is stable, if real number is = 0 it is marginally stable, if real number is positive it is unstable

For pole z=o we can it is BIBO stable?
