Abstract :
Results on modeling quadratic systems described by Volterra series up to order two are presented. Specifically, expressions for the linear and quadratic transfer functions and the system coherency are derived. It is shown that all the three quantities can be independently computed in the discrete frequency domain in terms of various spectral moments
