See Hi, can anyone help me.. how to find transfer function of theta band EEG?
You can change the passband and stopband frequencies of the theta band filter by defining the passbands for each EEG band and then setting the lower stopband to 1 Hz below and above (respectively) the passband frequencies. Remember to change the sampling frequency ‘Fs’ to the one you are using.
