Description
A time series can be 'phase scrambled' by randomly reordering the Fourier components in the frequency domian, and then inverse Fourier transforming. This procedure will produce time series that are unrelated to the input time series in all ways other than having the same power spectrum.
Usage
1
phase_scramble(fft_of_signal)
Arguments
fft_of_signal
The forward Fourier Transform of the timeseries: fft_of_signal <- fft(signal)
Value
series_scr
The phase-scrambled real-valued series
