EEG frequency bands

AcqKnowledge includes digital filters that allow you to filter a raw EEG into the following frequency bands:

Delta 0.5-4Hz

Theta 4-8Hz

Alpha 8-13Hz

Beta 13-30Hz

Gamma 36-90Hz (in some older versions the upper frequency is 44 Hz)

The filters may be selected and then modified for different frequency bands if desired.

Online procedure

When you start to record data you will see additional channels that contain band pass filtered versions of the raw EEG data.

Offline procedure

AcqKnowledge version 3.9.1 and above for Macintosh and version 4.0 and above for Windows fully automate the offline procedure for creating these additional channels.  Choose “Analysis > Electroencephalography > Derive EEG Frequency Bands” and follow the on-screen prompts.
