  We investigate a transition from chaotic to nonchaotic behavior and
synchronization in an ensemble of systems driven by identical random forces. We
analyze the synchronization phenomenon in the ensemble of particles moving with
friction in the time-dependent potential and driven by the identical noise. We
define the threshold values of the parameters for transition from chaotic to
nonchaotic behavior and investigate dependencies of the Lyapunov exponents and
power spectral density on the nonlinearity of the systems and character of the
driven force.
