SYNCHRONIZATION OF ELECTRIC FIREFLIES BY USING SQUARE-WAVE GENERATORS

In this article, we propose a square wave generator whose switching th reshold values are switched by external inputs. This circuit is design ed to simulate the synchronized luminescence of coupled fireflies. We investigate the behavior of the solutions in two coupled oscillators. The dynamics are demonstrated by a linear autonomous equation piecewis ely, therefore. a one-dimensional return map is derived. We also prove the existence of stable in-phase synchronization in the coupled oscil lator by using the return map, and we show the existence of regions of periodic solutions within a parameter space. Some theoretical results are confirmed by Laboratory measurements.
