I read somewhere that all non-periodic signals are Energy signals & periodic signals are power signals.
But then I came across the step function (u(t)) which is also non periodic but it is a power signal.
This made me wonder whether u(t) really is non-periodic? I mean, are all the signals classified as periodic & non-periodic? Is there no exception where the signal belongs to neither?
And can someone explain why u(t) is power signal despite being aperiodic?
Thanks~
