Identity Recognition Using Biological Electroencephalogram Sensors

Table 1

Five frequency bands of EEG signal.

Activity	Frequency (HZ)	Characteristic of signals	Behavior
Delta	0.5–4	Slow wave	Sleeping
Theta	4–8	Slow wave Low frequency	Falling
Alpha	8–13	Fast wave	Relaxing
Beta	13–30	Fast wave high frequency	Psychical activity
Gamma	30–40	Fast wave high frequency	Stress mechanism
