Frequency domain modeling of dual-input/multiple-output quadratic systems with general random inputs

A digital method of estimating linear and quadratic transfer functions of a dual-input/multiple-output quadratically nonlinear system with general random inputs is described. The approach is based on a frequency-domain second-order Volterra functional series representation for a dual-input/multiple-output system. The feasibility of the approach is demonstrated with the aid of a computer simulation for a known system.<<ETX>>
