Extracting Peak Alpha Frequency and IAF
Posted: Mon Oct 18, 2021 11:41 am
Dear all,
I'm sorry if this subject has already been treated, yet i found nothing on it.
My question is pretty simple : i'm trying to find a way to assess peak alpha frequency in real time (frequency corresponding to max(pow) in alpha range), to use it as my main BCI parameter.
Is there a function i'v missed to do so ?
Another related question : if i want to assess the true individual alpha frequency (IAF) defined as
IAF = Sum(Pow(f)xf) / Sum(Pow(f))
Is it possible to get the power at each frequency bin in real time and process the formula above in a simple DSP box ?
Thank you very much for all your help
Cheers
