RESUMO

A technique is suggested for detecting quadratic type nonlinearities of random processes in the presence of additive noise. The method is based on the application of «1½D-spectra», Γ(w ), of the process. Equations for the mean value and variance of Γ(w ) have been derived.
An algorithm is developed to determine the nonlinear transformation factor for a noise spectrum of unknown uniform density in the frequmcy band of analysis.
