Fourier Spectrum of Chaotic Oscillations in Autonomous Auto-Stochastic Systems with Multisegment Nonlinearity

Properties of the frequency spectrum of chaotic oscillations in autonomous autostochastic systems with the multisegment nonlinearity are considered. A component of the oscillations is extracted which determines their dependence on a number of nonlinearity segments. It is shown that a frequency function of Fourier spectrum of this component corresponds to a function of 1/f and may be approximated by a spectrum of the multistep random pulse function.
