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?

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));
