Notch filter #421

Open nmhettema opened 3 years ago

nmhettema commented 3 years ago

The current version does not have a notch filter module available. Is it possible to implement this? Think this would be very usefull to filter out 60 Hz noise in ephys recordings. a 2014 version of Open Ephys contained a notch filter, but this was never merged in the newer version it appears.

This should be fairly straightforward to add. In the meantime, have you tried using a Common Avg. Reference? That may be sufficient to remove the 60 Hz noise you're seeing.
