Abstract

The frequency Responce Function (FRF) of the best linear approximation to a nonlinear system is usually measured by averaging system responces to a normally distributed, filtered and clipped random excitation (Gaussian noise). This signal is compared to the multisine signal with random phases. It is shown that a random phase multisine signal defined over an even-odd frequency grid is superior to the Gaussian signal in terms of the variance and the bias of the measured FRF of the approximated nonlinear system.
