摘要
以定理的形式给出了具有量化和溢出非线性的二维递归数字滤波器不存在零输入极限环的充分条件,并证明这些定理比现有的定理更具有一般性.给出的检验定理可用于检验具有多重和复合非线性的二维递归数字滤波器的极限环情况.
Sufficient conditions for the nonexistence of zero input limit cycles in 2-D recursive digital filters with quantization or overflow nonlinearities are presented in form of theorems.They are shown to be more general than those already presented and can be used to test the 2-D IIR filers with multiple or complex nonlinearities.
