+ Q1 (d) A voltage signal may be represented by the Fourier series given as 10 20 1 v(t) = Σ. sin(2n-1)0,1 2 (2n-1) Determine the DC value, and the rms values of the fundamental and the third harmonic of this signal. Solution: (e) A voltage signal has the finite Fourier series representation: v (t) = 4 + 12 cos (3141) + 8 sin(2x 1501) Q1 (i) Sketch to scale the double-sided amplitude line spectrum of the signal. Qile (ii) [ii] Use Parseval's theorem to determine the normalised average power in the signal. Solution: Q1 Tota
