摘要: In this paper, we study the signal amplification of coupled active rotators with phase-shifted coupling. We find that system’s response to external subthreshold can be significantly affected by each two types couplings: identical and non-identical couplings. Moreover, through both theoretical analysis numerical simulations, have figured out optimal phase shift, at which largest is generated. These results show coupling plays an important role in regulating signal.
