We have constructed an electronic circuit which accurately mimics the dynamics of a nonequilibrium, bistable flow driven by additive, exponentially correlated, Gaussian noise. The noise voltage and voltages representing the velocity and displacement were measured, digitized and then assembled into the stationary, statistical densities W(Vn,X) and W(Xdot,X) for several noise intensities and correlation times. Our measurements are in good agreement with the theoretical results of Jung and Risken described in the preceeding paper.
