hi, i mdoing project on BRAIN COMPUTER INFACE , and it is n the Initial stage.
i have got a an EEG signal wav file on net (after searching), and working on it.
The signal frequency is 100hz, and i want to bandpass 12 hz to 18 hz.
To achieve this , i find FFT first ,samopling frequency is 200hz. now i want to see my reqired ferquencies in HERTZ.
Q: How to convert /normalize my FFT , to get my reqired signal.
please hlp me, i m in really trouble, help me
best regards
