Q3(iii) Fourier transform of a signal Consider the pulse shown in Figure 03. p(t) M А -T T [s] Figure Q3: A Pulse p(t) = Auot+T) - Auolt-T) e) Select the properties that will be used to find the Fourier transform pair p(t) = P(jw) Frequency shifting Symmetry Time shifting Time/Frequency Scaling Linearity Time convolution Subm Une f) Use the properties selected in parte) and the result of part d) to write down the Fourier transform of P(jw) when A=3 and 7=5. Show steps you will lose 1 mark.) Answer: Subm Un g) If the pulse is delayed by 45 seconds, compute the Fourier transform of pſt - 45). Show steps you will lose as marks) Answer: Subm Un:
