Question 4 50 Marks This question examines discrete-time filters. A filter of the form G(z) = with poles defined by p reun will be studied. Part (a)25 Marks With r 0.95 and w -T/10, plot the time response to the input clean sinusoidal waveform generated in the previous question. Show both the transient (initial) and steady-state (after the initial transient) responses. Part (b) 25 Marks Plot the frequency response of the filter. Explain all your working, particularly how the transfer function is converted to gain/phase plots Find the gain and phase from the time-domain response of part (a), and compare to that expected from the frequency response in part (b). Compare the results obtained using these two methods Show transcribed image text
