[FieldTrip] Filtering and oscillations

[Rodolphe Nenert]

Dear Fieldtrippers,

i have a theoretical question.
Im interested into phase-lock analysis between sensors in alpha
oscillations.
Prior to do so, my data were bandpassed between 2 and 30 Hz. However, i
heard that such a low-pass filter can alter informations usefull to
phase-lock analysis.

Any suggestions on that?
Best regards,

Rodolphe.
