Hi guys,
I have this question in the book whether a signal is Power Signal or Energy Signal.
From what I have read signal is an energy one if its time-averaged power is = 0, or its non periodic.
For non-periodic signal
V(t) [tex] \neq[/tex] V(t+T)
I tried to prove that
[tex]V(t) = 230\sqrt{2} Sin (100\pi t)[/tex]
is non-periodic.
So I picked random values for t=1 and T=1, and I got this eqn:
[tex]230\sqrt{2} Sin (100\pi)=230\sqrt{2} Sin (100\pi+1)[/tex]
Which states that it's non-periodic, ie V(t) is an energy signal.
Now I have an impression that this is not right. Can anyone help me? Book I have is no good with examples.
Plus if anyone could send me a link where there are some examples with Energy, Power, Periodic and Non-Periodic signals?
I'm using "Signals and Systems" by S. Haykin and B. Van Veen.
Thanks guys!
