Analytical determination of autocorrelation and noise power density spectrum of randomly modulated pulse width square waves
The Wiener theory of the minimum mean square error ·criterion is well furnished by knowing the autocorrelation function of the input to the linear system. This input signal is generally an additive mixture of a piecewise continuous message and a noise. The problem considered in this paper is the …

A theory of nonlinear systems
… an impulse since superposition does not apply. Wiener has shown, however, that we can characterize a nonlinear system by a set of coefficients and that these coefficients can be determined from a knowledge of the response of the system to shot noise excitation. Thus, shot noise occupies the same …

An Investigation into Nonlinear Random Vibrations based on Wiener Series Theory
… the behaviour of nonlinear systems using the ‘Wiener theories’. As a useful example the Duffing oscillator is investigated in this work. In many real-life applications, nonlinear systems are excited randomly so this work examines systems under white-noise excitation using the Wiener series. …

Statistical Vibro-Acoustic Modelling of Nonlinear Systems with Applications in Vehicles
… of weak acoustic coupling and the infinite plate theory. Numerical data in the time domain were generated from the simplified nonlinear system excited by random inputs with known power spectral density. The effects of nonlinearities were observed and quantified in the power spectral density of the …
