Abstract :
This paper is concerned with the Volterra-Wiener theory of nonlinear time-invariant systems with memory, based on Volterra series expansion. We present an approximating approach to the Wiener formulation of nonlinear systems that is able to represent such systems with an arbitrary given error. In addition, it is proven that this scheme is particularly suitable for an analog circuit implementation
