Abstract :
In this paper the stability of the fundamental frequency of 16.7 Hz of European railway networks is observed and its influence on processing higher order harmonics is evaluated. The stability is analyzed by means of amplitude frequency spectrum, short-time Fourier transform and residuals of sine-wave fitting.
