(b) The system function of a filter is 4+3z-' + 5z2 1-62-1+2= (i) Draw any structure to realize the above filter. (ii) Count the number of adders, multipliers, and delays used in your structure. (7 Marks) (c) A discrete-time IIR (infinite impulse response) filter H(2) has to be designed from a continuous-time IIR filter H. (s) using the bilinear transformation method. (i) Let the required specifications for the discrete-time filter H(2) be $0.95 <| H(e)s1 for 0S052.1 || H(e) 50.08 | for 2.550ST Determine the required specifications for the continuous-time filter H (S). (ii) It is given that H.(5) 3 s2 - 2s +3 satisfies these specifications. Find H(z). (iii) Find the resulting cutoff frequency cutoff of the discrete-time filter H(z) if the continuous-time filter H (s) has a cutoff frequency Sextof = 2 rad. (10 Marks) cutoff
