(a) Figure 1 shows time and frequency domain representations of a single rectangular non- periodic pulse (60 marks); s(f) volts HZ s(t) volts - A Hz ܙ | seconds Figure 1: Time and frequency domain representations of a single rectangular pulse i. Show that ii. s(t)= At sinc (neft) [20 marks] Determine the expression for normalized energy spectral density ( )of a single rectangular pulse and plot the spectrum. [20 marks] iii. Given that the average normalized energy spectral density for a series of non-periodic pulses Y e (f)= naʼrsinc? (ft), Relate the given equation to find the expression for the average normalized power spectral density G(f) for the series of non-periodic pulses and plot the spectrum. [20 marks)
