Frequency bands extracted from the wavelet coefficients and grouped into corresponding frequency bands. The respective frequency bands are derived by finding the mean of the respective wavelet coefficient vector.
| Wavelet Coefficients | Frequency Range | Frequency Bands |
|---|---|---|
| W6,1–W6,5 | 0 Hz–4 Hz | Delta |
| W6,6–W6,10 | 4 Hz–8 Hz | Theta |
| W6,11–W6,17 | 8 Hz–13 Hz | Alpha |
| W6,18–W6,45 | 13 Hz–20 Hz | Beta |
