Iterative computation of nonlinear transfer functions for discrete nonlinear system

研究了基于Ｖｏｌｔｅｒｒａ级数的一类离散非线性系统的非线性传递函数的递推算法，首先讨论了几类特殊的非线性系统如纯输入、纯输出和纯交叉系统的非线性传递函数的递推算法，然后给出一般的离散非线性系统的非线性传递函数的递推算法．

The iterative computation of nonlinear transfer functions for a class of discrete nonlinear systems is presented.Thes method is based on Volterra series and multivariable Z transform .The iterative computation is first discussed of nonlinear transfer functions for some special nonlinear systems such as the pure input,the pure output and the pure cross product nonlinear systems,and then the iterative computation is given of nonlinear transfer function for general discrete nonlinear system.
