<div dir="ltr">Dear Ida,<div><br></div><div>The function eegfilt() provides a bandpass filter option. Please check it.</div><div><br></div><div>BTW, the resolution of the frequency in the spectrum varies according to the amount of your actual data point. Adding more data if you need higher resolution. </div>
<div><br></div><div>Best</div>

<div dir="ltr">Dear List,<div><br></div><div>I would really appreciate any opinion of what would be the best way to extract certain frequency from the dataset of EEG recordings with the boundaries as narrow as possible (+-0.5Hz)?</div>
<div><br></div><div>In frequency domain it would be a bandpass filter that is reversed notch filter but there is no such option in EEGLAB. Which of the offered filters would be the most appropriate and with what parameters?</div>
<div><br></div><div>I am aware of the fact that any filter would distort data in certain way so it would be good to have as minimum as possible distortion.</div><div><br></div><div>Thank you very much</div><div><br></div>
