2.10-2. Consider the system described by x(k + 1) = (a) Find the transfer function Y(z)/U(z). y(k) =[-2 1]x(k) + (b) Using any similarity transformation, find a different state model for this system. (c) Find the transfer function of the system from the transformed state equations. (d) Verify that A given and A,, derived in part (b) satisfy the first three properties of similarity transforma- tions. The fourth property was verified in part (c).
