How to convert dB to Hz
What is the relationship to Hz from dB on the raw page?
Re: How to convert dB to Hz
The RAW EEG shows voltage from the sensor electrodes, not frequency or power (bels).
On a super basic level, this is how the math/graphs work:
RAW EEG voltages -> FFT calculation and binning -> Discrete frequency graph with powers per frequency -> Grouping of frequency powers -> Absolute Graph.
