In this work, we experimentally investigate the robustness to noise of synchronization in all the four-nodes network motifs. The experimental setup consists of four Chua's circuits diffusively coupled in order to implement the six different undirected network motifs that can be obtained with four nodes. In this experimental setup, synchronization in the presence of noise injected in one of the network nodes is investigated and network motifs are compared in terms of the synchronization error obtained. The analysis has been then extended to some selected case studies of networks with five and six nodes. Numerical simulations have been also performed and results in agreement with experiments have been obtained. A correlation between node degree and robustness to noise has been found also in these networks.
在这项工作中，我们通过实验研究了噪声对所有四个节点网络模式的同步鲁棒性。实验装置由四个 Chua 电路扩散耦合而成，以实现可以通过四个节点获得的六种不同的无向网络模式。在这个实验设置中，研究了在噪声注入到网络节点之一的情况下的同步，并根据所获得的同步误差比较了网络模式。然后，将分析扩展到具有五个和六个节点的一些选定网络案例研究。还进行了数值模拟，并获得了与实验一致的结果。在这些网络中也发现了节点度与噪声鲁棒性之间的相关性。
