Dear members,<br><br>My question is that how can I filter the EEG data at 0.01 cutoff frequency.<br>I have about 42,000 data potins (1000 sampling rate for about 7 minutes).<br>When I use 'basic FIR filter' menu with checking the 'plot the filter frequency response', <br>
(filter order was either 5000, 10000, or 100000 points) the cut-off curve occurs approximatley at 1 Hz in all cases.<br>It's there any methods for 0.01 high pass filter?<br><br>Best,<br>HanGue.<br><br>
