The problems of limit cycles in second-order recursive digital filters with a rounding off quantizer have been studied more systematically in this paper. 本文比较系统地研究了具有单舍入量化器二阶递归数字滤波器的极限环问题。
In this paper the zero-input stability of second-order digital filters with a rounding quantizer has been analyzed by the properties of limit cycles. 本文根据极限环特性对单舍入量化器二阶数字滤波器的零输入稳定性进行了分析。
