The Volterra Series and its Application

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