WebAug 14, 2012 · 9. The MatLab function hilbert () does actually not compute the Hilbert transform directly but instead it computes the analytical signal, which is the thing one needs in most cases. It does it by taking the FFT, deleting the negative frequencies (setting the upper half of the array to zero) and applying the inverse FFT. http://www.ece.northwestern.edu/local-apps/matlabhelp/toolbox/signal/downsample.html
