Networks of IFOs with various pulse-frains : analysis, synthesis and application to information communication.

1)提出了一种适用于多路输入的简单积分点火振荡器(IFO)。我们用一种新颖的方法分析了单输入形式的IFO不能观察到的新的尖峰间期共振现象所代表的基本现象。2)利用IFO构造了一个脉冲耦合网络(PCNN)。我们对PCNN的基本同步现象进行了分类，并阐明了每个现象产生的参数条件。3)考虑到同步现象与信息分类函数之间的相关性，构造了一个简单的多路通信系统，其中使用了脉冲间隔调制。4)我们提出了一个简单的尖峰振荡器(CSO)，它有两个状态，表现出包括混沌在内的各种脉冲串。阐明了基本的分叉现象。5)对耦合CSO的基本同步现象进行了分类，明确了每个现象产生的参数条件。6)提出了PCNN和SCO的简单实现方法。压控电流源和电容是实现该方案的基本元件，并在实验室中验证了典型现象。

1) We have proposed a simple integrate-and-fire oscillator (IFO) to which plural inputs are applicable. Using an original method, we have analyzed the basic phenomena represented by novel resonance phenomena of inter spike intervals which can not be observed in the single input version of the IFO.2) Using the IFOs, a pulse-coupled network (PCNN) is constructed. We have classified basic synchronous phenomena of the PCNN and have clarified parameters condition for generation of each phenomenon.3) Considering relevance between the synchronous phenomena and information classification function, a simple mnltiplex communication system is constructed, where pulse interval modulation is used.4) We have proposed a simple spiking oscillator (CSO) which has two states and exhibits various pulse-trains including chaotic one. The basic bifurcation phenomena are clarified.5) We have classified basic synchronous phenomena of the coupled CSOs and have clarified parameters condition for generation of each phenomenon.6) Simple implementation methods of the PCNN and SCO have been proposed. Voltage-controlled current source and capacitor are basic elements for the implementation and typical phenomena are verified in the laboratory.
