20 Hz QUESTION 4 MARKS: 25] A particular DSP system with a sampling frequency of Hz has the following transfer function: Z + 1 T(2) Z -0.25 = Q 4(a) [6 Marks] Plot the pole-zero diagram for this system. Mark in points A and B and C for frequencies of 0 Hz, 5 Hz and 10 Hz respectively. [4 Marks] Q 4(b) Calculate the gain and phase of this system at OHz. Note: II ZeroDistances Gain = II Pole Distances Phase Angle = {ZeroAngles - PoleAngles = [15 Marks] Q 4(c) Calculate the gain and phase of this system at 5Hz. [End of Question 4]
