Analysis of Best Linear Approximation of a Wiener-Hammerstein System for Arbitrary Amplitude Distributions

For a nonlinear system with an input signal having a Gaussian probability distribution (this includes random-phase multisines), the best linear approximation (BLA) is proportional to the frequency response of the overall system. However, this is not the case for non-Gaussian input signals, for which...
