Analog simulation has led to the observation of the reciprocal stochastic synchronization of
dissipatively coupled self-excited noise generators. The chaotic behaviors of oscillators with
different parameters coincided almost completely, and synchronization occurred in the case
of sufficiently strong coupling. Ensembles of parametric noise generators were used to
construct an approximate theory of noise generation.

Mutual stochastic synchronization of dissipatively coupled self-excited noise oscillators was
detected experimentally on an analog modelling apparatus. The phenomenon consists in an
almost complete coincidence of the chaotic realizations of oscillators with various
parameters and is observed at a sufficiently high degree of coupling. An approximate theory
of stochastic synchronization is constructed for the case of an array of parametric noise
oscillators. I. Unlike mutual synchronization of periodic oscillation, which today seems …
