I have very limited knowledge of DSP, so I apologize if my question is trivial :)
I have an EEG signal from which I need to extract different frequency bands. For example, waves in the the frequency band of 8-12 Hz.
After noise filtering, I was planning to simply feed the data into the FFmpeg bandpass filter, setting the 'frequency' to 10 Hz, and 'width' to 2 Hz. Is this the way to do it?
I need to ask this since I'm not sure how to check if I got the correct wave in the end.
