6. Consider the function in the s-domain

10 Y(s) = s(s+2)(s+6) Let T be the sampling time. Then, in the z-domain the function Y(s) is 5 N 5 a. Y(z) = Z 5 Z 6 z-1 4 z-e-27 + 5 b. Y(z) = N 5 Z + 6 z-1 5 N c. Y(z) = 6 z-1 4 z-e-67 + 5 12 z-e-67 5 12 z e- z-e-67 12 z-e-27 Z z 1 d. Y(z) N Z 5 Z = + 6 z 1 1-e-2T 61-e-67
