Abstract
This paper describes realization of mutual entrainment simulating synchronous flashing of fireflies. To simulate synchronous flashing of fireflies, we invented self-excited oscillator consists phase delay element, amplification element and saturation element. For a general design of self-excited oscillator, we made the characteristic between the input and the output to self-excited oscillator linear transfer function. We developed the technique for requesting a synchronous area and the phase difference that is a synchronous characteristic by using a linear transfer function. We produced an electronic firefly with the electric circuit and reproduced the phenomenon similar to synchronous flashing of fireflies.
