NTEegIndexChannel

The class of the data channel of the EEG signal indices. The channel determines the rhythms by the EEG signal: alpha, beta, delta, theta. It inherits from the base channel class NTBaseChannel. Notification of new data in the channel is carried out only when the device is connected and the signal is being picked up.
