Dear Bitalino team,
I spent a while testing different setups and electrodes.
The following is related to tests that I performed with pre gelled sticky electrodes (TIGA-MED Gold).
I attached the Electrodes as supposed in the video you have posted.
I did many attempts and gathered data over a period of 2-10 minutes.
In the attachment you can find some datasets that show how my data looks like.
It seems like I am not detecting EEG.
Can you please help me on this?
If I perform an FFT Analysis it looks like the brainwaves from 0-4 Hz are the most active ones in every situation which should not be the case.
I calculated the single sided FFT according to this Matlab page: https://de.mathworks.com/help/matlab/ref/fft.html
I attached the FFT comparisons between the three posted signals.
What am I doing wrong?
Edit: The data was detected with 200 Hz sample rate.
