The present invention refers to a reverse filter of the pth order, p being a positive integer number, of a non linear system modelled by means of a Volterra filter, implemented by means of the cascade of the reverse filter of the linear part of the model and of p-1 cascaded cells; the main characteristic consists in the fact that each one of said cells comprises a first branch where there is present the output signal of the reverse filter of the linear part, and a second branch constituted by the cascade of the non linear part of the model and the reverse filter of the linear part of the model. Eliminating the reverse filter in cascade with the p-1 cells pre-linearizing and post- linearizing filters are obtained.
