FFT spectral analysis can be employed to extract EEG signals from various frequency bands. The extracted signals enable diagnosis of neurological disorders and analysis of brain electrical activity and functional states. Implementation involves: 1) Converting experimental EEG data files (pre-processed with 50Hz notch filtering) to text format (e.g., 0661.txt) for MATLAB compatibility; 2) Importing data into MATLAB, extracting Fp1 channel signals, applying FFT to isolate α, β, θ, and δ bands, and performing inverse FFT for time-domain reconstruction; 3) Calculating power spectral density for each frequency band.
