A key consideration is whether you want to specify the order of your filters? Are do you want MATLAB to find the minimum order filters that meet your specifications?
(2006)51. LFP was first band-pass filtered using an infinite impulse response (IIR) Elliptic filter by means of the “filtfilt” function (Matlab). Then the Hilbert transform (Hilbert function, Signal Processing Toolbox) was used to compute the instantaneous beta (15–35 Hz) or gamma (...
