EEG Data processing in MATLAB

EEG data will be made available in .edf format.
Your job is to do the following in MATLAB:
1. Export EEG data in MATLAB.
1(a). Remove noise and other artefacts
2. Apply Hamming window for the filtered signal.
3. Use Elliptic band-pass filter [1.5-45] GHz
4. Call the MATLAB function of elliptic filter to extract Theta, Alpha, Beta, Beta-Low, Beta-High, and gamma bands.
5. Plot the individual bands.
6. Get FFT and calculate Power Spectral Density of the bands.
7. Calculate and plot PSD of Alpha, Beta-low, Beta-High, Gamma, Alpha/Beta, Alpha/Theta, Theta/beta, Alpha/(beta+Gamma), (Theta/Beta+Gamma)
