We're given this 'interactive page' that gives us the values, so T=2.8066, W=0.9542 and A=8.5988 and then told to find a0, b0, a1, b1, a3, b3, Total Power and 3rd harmonic power.
Cn given above and:
a0=1/T [tex]\int s(t) dt[/tex] integrating from 0 to T.
The Attempt at a Solution
I can't find a way to use the Cn forumla given, since sinc(x)=sin(PIx)/PIx, where x=nfW, and you can see why I can't use it if I want to find c0. So I go to the usual formula for a0, involving the integral, i use that and end up with: a0=8.5988 which is my amplitude and the web page where we have to input our values tells me that I'm wrong. I don't know what I'm doing wrong here?
I can find a1 and a3 easily from the Cn formula (and since Cn=An/2), all the b values=0, since it's an even signal, so I'm stuck with a0?
Also how would I go about to find the total power?
