filtering EEG data - notch filter
Posted: Wed Jan 13, 2021 5:06 pm
Hello,
I wanted to ask something regarding data filtering. I use Unicorn EEG device from g.tec and I am sending the data through LSL to OpenVibe. I send the data out from OpenVibe as OSC message to the network and receive it with another program in order to program sound.
I am trying to do some filtering in between and I managed to add bandpass filter (0.5-30Hz) which works nicely,
but I also want to add 60Hz Notch filter. I don't know how to do this. Shall I take the same temporal filter? I tried this but probably it doesn't make sense:
Could you please help me with this? I want my data to be a little bit more stable because now I feel like there is still too much noise and I can't trust it. All insights of how it could be improved are highly welcomed!
Thank you very much.
Best,
Kamile
