Question 5 (20 marks) a) Consider a periodic signal x(t) with period T defined as x(t) = = Compute the Fourier series coefficients of signal x(t). b) A single sideband modulated wave s(t) is applied to the coherent detector shown in Figure 4. The cut off frequency of the low pass filter is set equal to the highest frequency component of the message signal. Using frequency-domain ideas, show that this detector produces an output that is scaled version of the original message signal. You may assume that the carrier frequency we satisfies the condition we > Wm' (10 marks) SSB modulated - signal s(t) Product modulator Carrier Ac cos(wct) Figure 4 -e-st, -<t<0 t, 0 < t < 1/ (10 marks) Lowpass filter →Output
