WebThe most generalized way of measuring periodicity of a signal is to take it's Fourier transform, use it to get a power density distribution, then normalize this distribution to obtain something... WebAmplitudes of the Fourier transform of the network variance. The plot is consistent with a lack of periodicity in the data. Fourier amplitudes are calculated for the time-ordered sample variances of network Z-scores. The continuous data extends from Jan. 1, 1999 to Sept. 7, 2001. The plot shows the first 5000 amplitudes of the series.
