EEG in Hertz


#1

I am currently studying the EEG data get from Muse 2016.
As I known the EEG data get from Muse headband is in microvolts unit
or the relative data get is in bels unit…
May I ask is it possible to convert the EEG data into hertz unit for calculation?
Your answer is much appreciated, thank you

Calculating discrete frequency values from raw EEG data is a little complex, but if you’re interested in how to do it, here is a link to the source code to do it in pretty much every single programming language.

If you don’t know how to code, then my advice would be to ask a friend who does know to help you, as FFT’s will be a little daunting as a first step into the world of code.


#3

Is it means if I need to calculate the frequency I need to use the FFT to do it?


#4

Correct.

Thanks for your information…I have look through the code you have given…May I know if I use FFT to calculate EEG, what will be my input of FFT calculation?


#6

Raw EEG sets in, frequency sets out.


#7

Ok, thank you


#9

How to get the raw FFT per channel?
I have read through the API reference but did not see any class that have raw_fft value…
the museDataPacket has only the EEG, alpha, beta absolute and so on…but does not have raw fft value…

Dear
Your answer is much appreciated.
I have used FFT to calculate EEG, but the results is different than the FFTs calculated by MUSE,
Would know any reason why this might happen?
Thanks
