Dear eeglablist,<div><br></div><div>I would like to know whether there are any limitation or rules in filtering EEG data, or if there are someone who could recommend some papers about how high-pass filter change the data. </div>
<div><br></div><div>I have read some basic principles about how filter works, but still don't know how to choose a proper High-pass parameter to remove artifacts without distorting the data. I knew some researchers use 0.01Hz, some would recommend 0.1, 0.5 or 1Hz and some recommend not using High-pass filter at all. </div>
<div><br></div><div>The thing is, I found some participants' EEG waves in my experiments had large amount of slow drift, which could be removed by a 0.3Hz filter. However, I don't know whether that would distort the data greatly. What I want to observe are P300, N400 and P600 components as well as some sustained late negativity in ERP and also 3-70Hz in Time-Frequency domain. </div>
