Detailed Description

FFT for table columns.

vtkTableFFT performs the Fast Fourier Transform on the columns of a table. It can perform the FFT per block : this performs something close to the Welch method but it uses raw FFTs instead of periodograms. This allows to reduce the impact of noise as well as speeding up the filter when the input signal is too big.

It is also possible to apply a window on the input signal. If performing the FFT per block then the window will be applied to each block instead.

The filter will look for a "Time" array (case insensitive) to determine the sampling frequency. "Time" array is considered to have the same frequency all along. If no "Time" array is found then the filter use the default frequency value.

This filter will not apply the FFT on any arrays which names begin with 'vtk'.

This filter will consider arrays with 2 components as arrays of complex numbers, the first column representing the real part and the second the imaginary part.
