Özet

We investigate the possibility of generating higher order chaos via passive coupling of two identical or nonidentical sinusoidal oscillators. The examples of such a technique, which have already been reported in the literature, suffer from the lack of generality and apply only to particular sinusoidal oscillator circuits. Here, we treat sinusoidal oscillators either as generic single-port or two-port networks, and examine all the different coupling possibilities of any two stages. For this purpose, we choose the simplest possible coupling technique composed of two diodes: one of which represents a self-stage-controlled nonlinearity while the other represents an inter-stage mutually controlled nonlinearity. Experimental observations for selected coupling cases are shown.
