What is the difference between power signal and energy
signal?

Answer Posted / divyesh

1.Energy and power signals are both mutually exclusive,i.e they cannot occur simultaneously.
2.Enery signals amplitude value at -inf and +inf must approach 0. Power signals on the other hand have constant amplitude at both the entities.
3.All periodic signals are power signals.However the converse is not true.
4.Energy signals have 0 power while power signals have infinite energy.
5.Energy signal+Power signal=Power signal.
