Abstract :
In this paper we set up a framework to deal with nonlinear distortions in a linear modelling framework. The nonlinear system is replaced by a linear system plus a noise source. The properties of this representation are given, and a measurement technique to extract the linear model and the noise variance is developed. Eventually the different aspects of this approach are discussed from a measurement, an identification and a design point of view
