摘要
The influence of white and colored noise on the dynamics of self-sustained oscillator is considered in the regime of spiral (phase-coherent) chaos. The effective phase diffusion coefficient and power spectra are analyzed for noisy chaotic self-sustained oscillations. We show that chaotic oscillations can be synchronized by external narrow-band noise. Effects of chaos synchronization are compared for narrow-band noise signals with similar spectra but distinct probability distributions.
