Modeling non-Gaussian 1/f noise using stochastic differential equations and by sequences of stochastic pulses — •Bronislovas Kaulakys, Miglius Alaburda, and Julius Ruseckas — Institute of Theoretical Physics and Astronomy, Vilnius University, A. Gostauto 12, LT-01108 Vilnius, Lithuania
We present and analyze models of 1/f noise, which can be relevant for the understanding of the origin, main properties and parameter dependencies of the flicker noise. Signals represented as sequences of the random pulses [1] and models based on the stochastic differential equation with different relaxation rates [2, 3] are analyzed. The models generate signals with the Gaussian and non-Gaussian power-law distributions and 1/fβ power spectrum.
