Calculation of the original of response of multiinput nonlinear wireless devices using the Volterra series

A computing method has been proposed for calculating the original of response under the action of complex signals of multiinput nonlinear devices by using the tool of Volterra functional series. This method is based on the technique of determining Volterra kernels by differentiation of the system of harmonic balance equations and the procedure of transition to a single variable in the domain of transforms. A response in the time domain can be obtained by using the one-dimensional Laplace transform in the form of function of circuit parameters and input actions where the characteristics of nonlinear elements are approximated by an arbitrary analytic function. This study includes an example of computing the original of response of a nonlinear circuit with two inputs.
