The Devil's Staircase: The Electrical Engineer's Fractal

Abstract

In this paper, we describe an experimental technique for rapidly and accurately measuring the Devil's Staircase structure of frequency lockings in a periodically forced nonlinear oscillator. This technique uses a personal computer, a programmable oscillator, and a frequency counter. We include an analysis of the method, a discussion of its limitations, and experimental results for two simple test circuits. © 1989 IEEE
