AGC 付発振器の注入系に発生する "Noise-Induced Order"

This article gives an experimental approach to the problem of "What phenomena take place in an injection system of a chaos generating oscillator". First, it is shown that a practical putomatic gain controlled oscillator could exhibit period doubling bifurcation, chaos, and inverse period doubling bifurcation. Next, it is shown that a chaotic oscillation of such an oscillator could be transformed into a periodic oscillation by injecting period doubling-to-chaos waveform in another such oscillator. Especially some of this transition seems to be a kind of so-called "Noise-Induced Order".This article gives an experimental approach to the problem of "What phenomena take place in an injection system of a chaos generating oscillator".
