Recently, we have shown the emergence of oscillations in overdamped undriven nonlinear dynamic systems subject to carefully crafted coupling schemes and operating conditions. Here, we outline the existing theoretical results obtained on a system of N = 3 unidirectionally nonlinear elements; the oscillatory behavior is triggered when the coupling constant exceeds a threshold value (bifurcation point), and the oscillation frequency exhibits a characteristic scaling behavior with the “separation” of the coupling constant from its threshold value, as well as with an external target dc signal. We then introduce a different (asymmetric) coupling topology and demonstrate that it leads to an enhancement of the system response (quantified by a SNR) to an external target signal that is noise-contaminated. © 2007 American Institute of Physics [ABSTRACT FROM AUTHOR] |
