我们研究快速双稳态电子系统（一个隧道二极管）中的随机共振。我们在比先前实验所研究的更高的频率范围探究这一现象。报告了针对周期性信号频率的两个值（\(f_s = 1\)kHz和\(f_s = 10\)kHz）的输出信号的详细测量结果。我们在一种情况（\(f_s = 1\)kHz）下观察到一种非单调行为，其特征是在驱动信号频率下测量的输出噪声水平出现急剧下降。
We study stochastic resonance in a fast bistable electronic system: a tunnel diode. We investigate the phenomenon in a higher frequency regime than that studied in previous experiments. Detailed measurements of the output signal are reported for two values of the frequency of the periodic signal: ${\mathit{f}}_{\mathit{s}}$=1 kHz and ${\mathit{f}}_{\mathit{s}}$=10 kHz. We observe, in one case (${\mathit{f}}_{\mathit{s}}$=1 kHz), a nonmonotonic behavior characterized by a sharp dip in the output noise level measured at the frequency of the driving signal.
