$H(s) = \frac{s^2 + 7s + 10}{s^2 + 5s + 6} = \frac{-3.33}{s+5} + \frac{3.33}{s+2}$ Using Eq. (5.81b) we have $H(z) = T \left[ \frac{-3.33}{1 - e^{-5T}z^{-1}} + \frac{3.33}{1 - e^{-2T}z^{-1}} \right]$ $= 0.2 \left[ \frac{-3.33}{1 - e^{-5}z^{-1}} + \frac{3.33}{1 - e^{-2}z^{-1}} \right]$ $= \left[ \frac{-0.666}{1 - 0.3678z^{-1}} + \frac{0.666}{1 - 0.67z^{-1}} \right]$ $= \frac{0.2012z^{-1}}{1 - 1.0378z^{-1} + 0.247z^{-2}}$ Practice Problem 5.7 An analog filter has a transfer function $H(s) = \frac{5}{s^3 + 6s^2 + 11s + 6}$ Design a digital filter equivalent to this using impulse invariant method for $T = 1$ sec.
