System identification using almost periodic functions: application to non-linearities with memory

Abstract

A method for measuring by crosscorrelation the impulse responses of the linear portions of a system containing a zero-memory non-linearity is shown to be applicable to certain typos of non-linear characteristic with memory. Several situations are analysed and some experimental results presented. A computer programme is given for calculating the parameters of the input signal from a given tabulated non-linear characteristic.
