In analysis of nonlinear network responses

Volterra Series can be used to educe the nonlinear transfer function similar to the transfer function of linear systems.Via utilizing the nonlinear transfer function

it can make precision analysis for nonlinear system by using the methods of linearization and systematization.A set of continuous calculating formulae of nonlinear network responses was proposed based on the solutions of Volterra Series.In order to solve the problem of computing the continuous formulae

the block-pulse function transform was adopted to deal with the repeatedly computation of a set of generalized convolution integral which described the relationship between the nonlinear network response and its input by using Volterra series.This method could result in a set of discrete calculating formulae which could be used to obtain the response of nonlinear network based on the solutions of Volterra series.The results of simulation showed that the curve of nonlinear network response produced by this algorithm was very closed to the curve of the real model and proved the availability of the method.
