Determine the complex fourier series for $x(t)$.
Voltage $V(t) = V_0 \cos(\omega t) , ω = 100\pi(s^{-1}) $
Voltage input signal $x(t) = |V(t)|$
I was thinking to use Eulers formula to rewrite them, but the periodicity is a bit confusing for me. I first thought that with Laplace transform I could convert the $S^{-1}$ to the Heavyside step function , which gives me $100 \pi H(t)$.
So im thinking, am I supposed to ignore the $H(t)$ part, and just rewrite $\cos(100 \pi)$ to complex fourier, and then add the Heavyside ($H(s)$) or how would one tackle this approach?
Grateful for every reply!
