7. Setting up the system 

This  chapter  covers  the  case  of  using  SMARTING  to  record  EEG  signals. 
Similarly one can record other physiological signals. 

Note that the SMARTING amplifier is not compatible with other than passive 
type of recording sensors (passive electrodes). 

 

Figure 7.1

 Connect the amplifier to the cap. 

 

Figure 7.2

 Position the cap on the subject's head.
