摘要
The Frequency Response Function (PRF) of a nonlinear system under white Gaussian excitation is computed vp to O(P-2) in the power spectral density of the input P. The FRF qualitatively shows the expected shifts in resonant frequency and supports the observed fact that FRFs from random excitation are returned as linear system FRFs by the Hilbert transform test.
