摘要

本文研究了定点数字滤波器在2补态变量实现中的溢出振荡消除问题。提出了一种新的零输入不动点状态空间数字滤波器的全局渐近稳定性判据。与几个现有标准相比，所提出的准则更详细地捕获了2的补体溢出非线性的结构特性。将建议的标准与先前报道的各种标准进行比较评估。结果表明，所得准则没有现有的几个结果严格。最后给出了一个实例和仿真结果，验证了该准则的实用性。

Realisation of overflow oscillation-free fixed-point digital filters with 2’s complement arithmetic

ABSTRACT In this paper, we focus on the problem of overflow oscillation elimination in 2’s complement state variable realisation of fixed-point digital filters. A new global asymptotic stability (GAS) criterion for the zero-input fixed-point state-space digital filters employing 2’s complement overflow arithmetic is proposed. The proposed criterion captures the structural properties of 2’s complement overflow nonlinearities in a greater detail as compared to several existing criteria. A comparative evaluation of the proposed criterion with various previously reported criteria is made. The obtained criterion turns out to be less stringent than several existing results. An example along with simulation results to substantiate the utility of the criterion is also provided.
