I am Jungryul Seo who is researching on context-aware computing in graduate school, South Korea.
I have a little bit stupid question.
I collected EEG data using Muse 2014 version for researching and used calcuated value such as Alpha Absolute Power which were calcuated by Muse until this time.
Ah… today my supervisor advised me to calculate some features which Muse didn’t calculate.
In order to do that, I need to handle raw_fft0, 1, 2, 3 data for calculating.
In my best understanding, raw_fft0, 1, 2, 3 data are seems to be a result of FFT.
The above attached figure is a screenshot of captured data.
As we know, Delta frequency range is 1Hz ~ 4Hz. And, Muse 2014 frequency resolution is 0.86Hz.
Following to Muse Available data document, they said “The absolute band power for a given frequency range (for instance, alpha, i.e. 9-13Hz) is the logarithm of the sum of the Power Spectral Density of the EEG data over that frequency range.”
Following to document content, I treid to calculate Delta band absolute power, but I could not get same result of Muse calculate value.
I am confusing whether I did a mistake, misunderstanding or missing something.
Would you please anyone advise me about my problem?
