A great variety of natural and artificial systems exhibit chaos and frequency locking associated with quasi-periodicity. In this tutorial paper we present an overview of current theoretical and experimental work on quasi-periodicity. In Section I, we discuss the concept of universality and its relevance to experiments on nonlinear multifrequency systems. In Section 11, we describe the reduction of experimental data by means of Poincare sections, and the mathematical properties of thedoi:10.1109/31.1826 fatcat:ctlizhxbmvgd3c4jz7c34atpqe
