Abstract:
The system of two nonlinear stochastic equations simulating $1/f$ fluctuations during the interaction of nonequilibrium phase transitions in the presence of an external harmonic force is analyzed using numerical methods. It is shown that the stochastic resonance occurring in the system enhances the output periodic signal under the action of noise. A random process with a $1/f$ power spectrum corresponds to the Gibbs–Shannon information entropy peak. In stochastic resonance, the information entropy is minimal.
