Abstract

We describe two experiments in which we investigate the synchronization of coupled periodic oscillators. Each experimental system consists of two identical coupled electronic periodic oscillators that display bursts of desynchronization events similar to those observed previously in coupled chaotic systems. We measure the degree of synchronization as a function of coupling strength. In the first experiment, high-quality synchronization is achieved for all coupling strengths above a critical value. In the second experiment, no high-quality synchronization is observed. We compare our results to the predictions of the several proposed criteria for synchronization. We find that none of the criteria accurately predict the range of coupling strengths over which high-quality synchronization is observed. (c) 2000 American Institute of Physics.

摘要

我们描述了两个实验，在其中我们研究耦合周期振荡器的同步。每个实验系统由两个相同的耦合电子周期振荡器组成，它们会出现去同步事件突发，类似于之前在耦合混沌系统中观察到的情况。我们测量同步程度作为耦合强度的函数。在第一个实验中，对于高于临界值的所有耦合强度都实现了高质量同步。在第二个实验中，未观察到高质量同步。我们将我们的结果与几个提出的同步标准的预测进行比较。我们发现没有一个标准能准确预测观察到高质量同步的耦合强度范围。（c）2000美国物理研究所。
