It is demonstrated by analogue electronic experiment that the fluctuation spectra of single-well oscillators can sometimes display a twin-peaked structure. The results for the particular system considered confinn and illustrate for the fIrst time the earlier general prediction of zero-dispersion (additional) peaks in the spectra of underdamped systems possessing an extremum in the dependence of their eigenfrequency on energy. The corresponding large, noise-enhanced, susceptibility implies the existence of stochastic resonance in such systems.
