Q4(ii) Discrete-Time System The block diagram that implements a digital system H(z) is shown in Figure Q4(b). xin y[n] KI Z z x[n - 1] K2 K4 yn 1] Z Z xn - 2 ly[n- 2] Figure Q4(b) - Block diagram of digital filter Hz) The gains K1 ...Ky are tabulated in Table Q4 below. Table Q4: Values of Gain for the system of Figure Q4(b) Gain K Value 5 -15/8 -135/32 K2 K3 K, 0 K -9/64
d) Use the block diagram of Figure Q4(b) and the values of the gains Kitabulated in Table Q4 to write down the difference equation for the digital system. Answers may be entered as fractions. z[n]+[ 2[n-1]+ I[n – 21– y[n – 1] - y[n – 2] y[n] Submit part 1 mark Unanswered Q4(iii) The Z-Transform e) Take the Z-transform of the difference equation for part d) and hence write down the Z-transfer function: Y(z) (z) = X(z) = bo+biz-l+byz-2 1+4,2-1 + anz-2 You do not need to factorise the result.
