Abstract :
A description is given of an experimental technique for rapidly and accurately measuring the devil´s staircase, a structure of frequency lockings in a periodically forced nonlinear oscillator. This technique uses a personal computer, a programmable oscillator, and a frequency counter. The authors analyze the method, discuss its limitations, and present experimental results for two simple test circuits
