Calculate power values for each of the EEG bands: Delta < 4 Theta >=4 and < 8 Alpha >= 8 and < 14 Beta >= 14 and < 32 Gamma >= 32 and < 50

```

eeg_signal | EEG signal expressed in micro-Volts |
---|---|

sampling_frequency | Sampling frequency of the EEG signal. This is typically equal to 125Hz. Default value is 125. |

max_frequency | The maximum frequency for which the spectrum is being calculated. Default value is 32. |

num_sec_w | number of seconds in a time window used to obtain the Fourier coefficients. Typically, this number is 5 |

aggreg_level | number of 5 second intervals used to aggregate power. Typically, this number is 6 to ensure a 30 second interval window (standard in EEG analysis) |
