Abstract
Discrete-time processes that can be modeled by linear difference equations with time-varying coefficients can be written in terms of state variable descriptions of the form \(x(k + 1) = A(k)x(k) + B(k)u(k),\ y(k) = C(k)x(k) + D(k)u(k)\). The response of such systems due to a given input and initial conditions is derived. Equivalence of state variable descriptions is also discussed.
