摘要: This paper deals with the problem of global asymptotic stability fixed-point state-space digital filters under various combinations quantization and overflow nonlinearities for situation where occurs after summation only. Utilizing structural properties in greater detail, a new criterion is proposed. A unique feature presented approach that it exploits information about maximum normalized error quantizer representable number given wordlength. The leads to an enhanced region parameter-space, as compared several previously reported criteria.
