Q10) Consider a signal s(t) consisting of only three rectangular pulses as shown in Fig. Q10(a), with s(t) = 0 for t < 0 and for t > 3T. Let (f) be the Fourier transform of s(t). Write down the mathematical expression of S(f). (5 marks) s(t) A Fig. Q10(a) т 21 3Tt -A 10 Hint: The Fourier transform of the rectangular pulse x(t) in Fig. Q10(b) may be useful.
