The Fast Fourier Transform (FFT) is widely and standardly applied to raw EEG data to decompose signals and analyze their frequency spectra and power distribution.

The analysis

The claim that the Fast Fourier Transform is applied to raw EEG data to analyze frequency spectra is a standard methodological fact in neurophysiology supported by multiple retrieved studies, which use FFT to compute power spectral density and frequency representations from raw EEG signals.
