Chaos generation using binary hysteresis
A two dimensional dynamical system with hysteresis is considered. It is shown that an axis return map is continuous and has a periodic point of period three (for appropriate values of parameters). By Sharkovskij's theorem (the authors refer to the later paper of Li and Yorke) the dynamics of such a system has some chaotic features. The experimental results showing that such phenomena may occur in electronic circuits are given. In the authors' view, the pumping of the heart is of similar nature.
