Q13) Consider a signal s(t) consisting of only three rectangular pulses as shown in Fig. Q13(a), with s(t) = 0 for t < 0 and for t > 3T. Let S(f) be the Fourier transform of s(t). Write down the mathematical expression of S(f). [5 marks] s(t) A Fig. Q13(a) 0 T 2T 3T t -A Hint: The Fourier transform of the rectangular pulse x(t) below in Fig. Q13(b) may be useful.
