EegIndexChannel

#include “c_eeg_channels.h”

The data channel of the electroencephalographic (EEG) signal indices. The channel determines the rhythms by the EEG signal: alpha, beta, delta, theta. Heir to the base class of AnyChannel channels. Notification of new data in the channel is carried out only when the device is connected and the signal is being picked up

Description

create_EegIndexChannel	Function. Channel creation. Creates a data channel of EEG signal indices. Options: t3 Description: EEG signal data channel from overlapping area T3 Data type: EegDoubleChannel* t4 Description: EEG signal data channel from overlapping area T4 Data type: EegDoubleChannel* o1 Description: EEG signal data channel from overlapping area O1 Data type: EegDoubleChannel* o2 Description: EEG signal data channel from overlapping area O2 Data type: EegDoubleChannel* Return value: Description: index channel Data type: EegIndexChannel*
