Identification of Linear Systems with Nonlinear Distortions
TL;DR: A theoretical framework is proposed that extends the linear system description to include the impact of nonlinear distortions: the nonlinear system is replaced by a linear model plus a 'nonlinear noise source'.

The analysis of nonlinear systems in the frequency domain using Nonlinear Output Frequency Response Functions
TL;DR: The present study introduces a NOFRFs based approach for the analysis of nonlinear systems in the frequency domain by solving a set of linear difference equations known as the Associated Linear Equations (ALEs) to determine the system nonlinear output responses.

The effects of linear and nonlinear characteristic parameters on the output frequency responses of nonlinear systems: The associated output frequency response function
Yunpeng Zhu,Zi-Qiang Lang +1 more
TL;DR: It is shown, for the first time, that the output frequency responses of a wide class of nonlinear systems that are described by the NARX (Nonlinear Auto Regressive with eXogenous input) model can be represented by a polynomial function of both the system linear and nonlinear characteristic parameters of interests to the system analysis.
