The first spectral analysis of a spike event has been performed.It was found that the peak frequency of spectrum of the spike event on Oct.2,1993 drifted from higher to lower frequency for the first group of spikes,bu...
We derive a unified multi-harmonic modulation solution of the incommensurate phase with a simple model by a method like that used in solving pendulum problems in mechanics. This solution reduces to single-harmonic mod...
