The Volterra Series and its Application

The book delves into the modeling of weakly nonlinear systems through Volterra series analysis, establishing necessary conditions for their representation. It introduces a two-condition convergence criterion and a technique for deriving Volterra transfer functions. Additionally, it extends the analysis to systems with multiple nodes using a method of nonlinear currents, specifically applied to a MESFET amplifier. The discussion also includes approaches for quantifying nonlinear behavior, providing a comprehensive framework for understanding these complex systems.
