A plot of the Winding Number resulting from Mode Locking as a function of for the Circle Map with . At each value of , the Winding Number is some Rational Number. The result is a monotonic increasing ``staircase'' for which the simplest Rational Numbers have the largest steps. For , the Measure of quasiperiodic states ( Irrational) on the -axis has become zero, and the measure of Mode-Locked state has become 1. The Dimension of the Devil's staircase .
