I have a simple EEG signal in MATLAB such as that shown in the figure below. And what I wanted was to extract the components of the EEG according to the following table.
  • Delta - up to 4 Hz;
  • Theta - 4 -> 8 Hz
  • Alpha - 8 -> 13 Hz
  • Beta - 13 -> 30 Hz
  • Gamma - 30 -> 100 Hz
Any suggestions how I can solve the problem?

Hi,
I'm working on similar project as well. The way i do is restructure the binary data from hardware(RS232 Serial Port) , plot the value in time domain. Then, you may use FFT function to transform the signal into frequency domain. With that, just extract or segment the signal with respect to frequency.
Hope to hear from you and learn more ;)

How did you restructure the binary data?
