Question

1. Determine the period, and find the Fourier series coefficients for each one of the following signals: (a) $x(t) = 3 + 5 cos 2pi t + 6 sin(4pi t + frac{pi}{4})$ (b) $x(t) = -10 + 3 cos 2pi t + 7 sin 9pi t$ 2. A periodic signal $x(t)$ (with period $T_0$) is given by $x(t) = egin{cases} 1 & 0 le t le DT_0 \ 0 & DT_0 < t < T_0 end{cases}$ where $0 < D < 1$ is a parameter known as a duty cycle. Determine the Fourier series coefficients for this signal.
