2. a) Find the Fourier Series expansion for the signal x(t) given in Figure 1 theoretically. b) Transfer the resulted Fourier Series in (a) into Matlab software. c) Plot the signals in time domain for 5, 10 and 20 harmonics. d) Compare the signal both in time domain and frequency domain. The period of the signal will be given by your lecturer. x(1) 0 Figure 1 T
