Analysis of eeg for dection epilepsy

Hi everyone!

Im doing thesis for detection of epilepsy disorder by Discrete Wavelet Transform, I decomposed 6 levels, eeg is extracted 4 signal: delta(0-4), theta(4-8), alpha(8-12), beta(12-30Hz). But I dont know frequency band them, I want to check frequency band them right or wrong, can you help me?

thank you everyone!

Can you please share your code? I am facing difficulty in loading so many data files.

If you were able to extract all the sub bands then you can use this code to find out the frequency

D3 = detrend(D3,0); xdft = fft(D3); freq = 0:N/length(D3):N/2; xdft = xdft(1:length(D3)/2+1); figure;subplot(511);plot(freq,abs(xdft));title('GAMMA-FREQUENCY'); [~,I] = max(abs(xdft)); fprintf('Gamma:Maximum occurs at %3.2f Hz.\n',freq(I));
