On the Analysis of Quasi-Static Bandpass Nonlinearities Using Volterra Series

Abstract

This paper reexamines the AM-AM and AM-PM data-based behavioral model of a narrowband quasistatic nonlinear system via Volterra series analysis. It is shown that, under narrowband input signal and flat basedband impedance assumptions, the model is in compliance with bandpass nonlinearity theory. Consequentially, there exists a relationship based on the Chebyshev-Fourier transform between the nonlinearity's one tone and two tone AM-AM transfer functions
