I'm using the function to filter out line noise at 60 Hz (and 120, 180 Hz) caused by electrical noise: ecogNotch
For noisier electrodes, like below, I am unable to filter out the line noise with any range on my notch filter.
I understand that this is due to my notch-filter being gaussian in the frequency domain and my artifact exceeding all filter shapes significantly. Is there another way to effectively notch-filter out the extreme cases of line noise.
My two thoughts were either interpolating across the frequency domain or some sort of statistical baseline. I thought I'd ask here first to see if there is a well accepted answer for how to approach this.
