Correlation between the GVS signal and the estimated GVS artifact reconstructed from different frequency components.
| | Estimated GVS artifact without wavelet decomposition | Estimated GVS artifact from 0.12 Hz to 250 Hz | Estimated GVS artifact from 0.24 Hz to 125 Hz | Estimated GVS artifact from 0.49 Hz to 62.5 Hz |
| Correlation | 0.6960 | 0.8463 | 0.9168 | 0.9725 |
| | Estimated GVS artifact from 0.49 Hz to 31.25 Hz | Estimated GVS artifact from 0.49 Hz to 15.75 Hz | Estimated GVS artifact from 0.98 Hz to 31.25 Hz | Estimated GVS artifact from 0.98 Hz to 15.75 Hz |
| Correlation | 0.9776 | 0.9769 | 0.9899 | 0.9899 |
