It simulates a surrogate with similar Fourier spectrum for a given time series x analyzed
by wavelet transformation using either function `analyze.wavelet`

or function `analyze.coherency`

.
A set of surrogates is used for significance assessment to test the hypothesis of equal periodic components.

This code has been developed by Huidong Tian (archived R package `WaveletCo`

).

1 | ```
FourierRand(x)

`x` |
the given time series |

A surrogate series for x is returned which has the same length and a similar Fourier spectrum.
