I noticed with simulated input that ft_freqanalysis->ft_specest_wavelet
yields powspctrm results that are scaled by the sampling rate of the
The scaling factor appears to be (fsample/2). Of course, multiplying by
(2/fsample) corrects this.
Upon investigation I found that freqanalysis_mtmconvol (the predesessor
to ft_specest_wavelet (?)) from fieldtrip-20080624 contains this
correction factor on line 294.
1. What is this correction factor and why is it no longer applied?
2. Why is in not applied to the fourierspctrm output?
3. What, in general, are the output units of the
