Energy signal?????

hai..
i want to know why is energy signal having a finite energy value and 'zero value of power'
similarly the power signal have finite value of power and an INFINITE VALUE OF ENERGY :surprised

HINT(S):
1) (Average) Power = (Total) Energy / time
2) [tex]Energy=\int(Power)dt[/tex]
3) How much time do you calculate over?

it is the general concept irrespective of time

Yes, but a power signal lasts forever. A (finite) energy signal thus has 0 power. A power signal, because of how long it lasts (forever) will also have infinite energy. Unless there's 0 average power.
