Why the periodic signals are power signals? - Quora

WebA power signal is a periodic signal i.e. it has a time period. An Energy signal has finite Energy but zero power. And a Power signal has finite Power but infinite Energy. So a signal can be either energy signal or power signal but it cannot be both. An infinite signal that has no periodic nature is neither Energy nor Power signal. mumbai metro ticket online
