In this paper, two methods of distortion analysis are described. The Volterra series is usually used to determine nonlinear behaviour. The direct method is an extension of the Volterra series method to circuits with multiple inputs. The Volterra series method of distortion analysis is presented in the analysis of a common emitter circuit. Next the direct method is used to analyze a mixer circui...

This work builds on the Volterra series formalism presented in [D. W. Dreisigmeyer and P. M. Young, J. Phys. A 36, 8297, (2003)] to model nonconservative systems. Here we treat Lagrangians and actions as ‘time dependent’ Volterra series. We present a new family of kernels to be used in these Volterra series that allow us to derive a single retarded equation of motion using a variational princip...

This article presents a survey of various methods for nonparametric identification of nonlinear systems. Nonparametric identification methods are those that measure Wiener kernels or Volterra kernels, since an output of a nonlinear system can be described by the convolution integral of Wiener or Volterra kernels and the system input. Section 1 highlights the representation methods of nonlinear ...

We present a new mixed finite element method for class of parabolic equations with p-Laplacian and nonlinear memory. The applicability, stability convergence the are studied. First, problem is written in formulation as system one equation Volterra equation. Then, discretized space variable using Lagrangian basis degree r?1. Finally, Cranck-Nicolson trapezoidal quadrature applied to discretize t...

one of the most controversial and unresolved questions in bilingual first language acquisition (henceforth bfla) is whether bilingual children develop one mixed or two independent linguistic systems. many scholars in the lield of bfla arc in tavor of the one-system hypothesis (leopold 1970; swain and wesche, 1975; volterra and tacschner, j 987; grosjean, 1982; tacschncr, 1983: mclaughlin, 1984:...
