D.1) Synthesise and plot this square wave (provide your Matlab code as well). Calculate the percentage overshoot of the synthesised waveform (compared with the ideal waveform) at the discontinuity. How does this compare with the expected limit of 17.9%?

D.2) What is the name of this overshoot? Explain it

D.3) Give the Fourier series in each case for the resulting waveform if the above square wave is used as an input for:

D.3) (a) A low-pass filter with gain and phase responses as given in Figures 8 and 10 respectivelyD.3)

D.3) (b) A low-pass filter with gain and phase responses as given in Figures 8 and 11 respectively

(c) A band-pass filter with gain and phase responses as given in Figures 9 and 10 respectively.

D.4) Synthesise the above waveforms and draw the obtained waveforms for filters (a), (b) and (c), providing the Matlab code as well.
