Abstract
The paper presents the correlation functions and the spectral density of a random function as against its derivates that are relations of utility in the dynamic system’s study such the twin-tube shock absorber. There are determinate the response of mathematical waiting, the autocorrelation function response, the dissipation response, the spectral density response.
