We investigate non-Gaussian statistical properties of stationary stochastic signals generated by an analog circuit that simulates a random multiplicative process with weak additive noise. The random noises are originated by thermal shot noise and avalanche processes, while the multiplicative process is generated by a fully analog circuit. The resul...

... Leveraging these generators, realized, for example, using a resistor or diode, noise source circuits are readily obtainable, and can be easily combined with an additional stage providing the multiplicative effect, yielding power law effects [38,39]. Using this approach, the possibility of generating a multifractal time series using just two operational amplifiers was shown; however, this remains an isolated observation [40]. This paucity of multifractal signal-generating circuits in the literature is surprising also given that early papers on the f (α) formalism demonstrated broad spectra close to of chaotic transitions, in the attractor geometries generated by circuits such as driven diode-resonator systems and other apparatuses. ...
