Question:

Figure P.7.42 depicts an electric field in time and the Fourier components that compose it. The units are arbitrary. Given that

1 =–+ sin wt + 3 1 sin 2wt + -sin 3wt 6. 1 cos 2wt + 6. E(t)

(a) Explain why the series contains both sine and cosine terms.

(b) Why does the series contain harmonic terms having arguments with odd and even multiples of Ï‰t?

(d) What is the value of A₀?

(e) What is the value of the period of E(t)?
