在电路受到全局噪声影响的情况下，当工作在局部双稳态区域时，非线性电子电路的一维阵列被示出为支持脉冲的传播。这些外部随机波动被应用于控制单个电路中双稳态和单稳态动态之间的转换的参数。结果，在存在噪声的情况下，传播前沿变得不稳定，并且系统自组织以允许脉冲的传输。在弱耦合阵列中也可以观察到这种现象，即在没有噪声的情况下出现传播失败。
One-dimensional arrays of nonlinear electronic circuits are shown to support propagation of pulses when operating in a locally bistable regime, provided the circuits are under the influence of a global noise. These external random fluctuations are applied to the parameter that controls the transition between bistable and monostable dynamics in the individual circuits. As a result, propagating fronts become destabilized in the presence of noise, and the system self-organizes to allow the transmission of pulses. The phenomenon is also observed in weakly coupled arrays, when propagation failure arises in the absence of noise.
