Abstrakt:	The problem of exponential stability and the H ∞ performance criterion for externally disturbed state-delayed digital filter employing fixed point arithmetic in the existence of saturation arithmetic is highlighted in this paper. A limit-cycle free condition for a class of state-delayed digital filter in the existence of external disturbance and saturation arithmetic is brought out by employing Lyapunov function. The presented result ensures the exponential stability and scales down the consequences of external disturbances to the H ∞ performance index. A numerical example simulated using MATLAB linear matrix inequality control toolbox is provided to validate effectiveness of the achieved criterion. [ABSTRACT FROM AUTHOR]
