“…Anomalous behavior was observed for the tunneldiode voltage which obeys to the equation of motion for the overdamped oscillator in a bistable potential field W (u), where u is the output voltage, of the oscillator affected by a harmonic signal and noise. It is shown in [5] that the SR is also observed in the case where the voltage at the load resistance is picked up. Dynamic properties of the nonlinear system as functions of the signal amplitude are studied in [6].…”

“…This work is aimed at experimental study of the signal-to-noise ratio and its transfer coefficient and comparison with theoretical results [9]. In contrast to [4][5][6], the SR phenomenon is studied in the electric circuits with two and several tunnel diodes. Note that using several diodes, we can vary the form of the potential function W (u) over a wide range.…”

The signal and noise interaction in the first-order electric circuit with several tunnel diodes is studied experimentally. The signal-to-noise ratio and the transfer coefficient of the signal-to-noise ratio are obtained as functions of the noise intensity at the circuit input for different frequencies of the signal. It is shown that in the case of a symmetric and bistable potential, the earlier developed theory of linear response to the signal satisfactorily describes the experiment in the low-frequency range of signal and fails in the case of the high frequencies. The stochastic-resonance phenomenon is observed for a symmetric three-well potential. In the case of an asymmetric three-well potential, the double stochastic resonance stipulated by the presence of different-height potential barriers is observed. The transfer coefficient does not exceed unity in all studied systems.
