The second-order AR filter has feedback coefficients a1=0.9, a2=0.5 and b0 = 1. The value of the step response y2 = ________(x.xx).

Fill in the blank(s) with the appropriate word(s).


yi = 0.9yi-1 +0.5yi-2 + xi. With zero initial conditions and xi=ui:
y0=u0 =1
y1=0.9y0+u1=0.9(1) + 1 = 1.9
y2=0.9y1+0.5y0+u2 = 0.9(1.9) +0.5(1) +1= 3.21
