Asymptotic stability of discrete-time systems with saturation nonlinearities

The authors present results for the global asymptotic stability of the equilibrium x=0 of n/sup th/ order, discrete-time systems with state saturations. The results are used to establish conditions for the non-existence of limit cycles in n/sup th/-order fixed point digital filters. It is demonstrated that the present results are easier to apply and are less conservative than corresponding existing results.<
