### Rationale
Up to now, the `filter` task is mainly used for filtered backprojection, i.e. a one-dimensional, ramp-like filter in the Fourier domain. However, filtering has general purposes besides …

Widmann et al 2014 recomends not to use filtfilt, because cut-off frequency becomes dificult to estimate etc.
I also wouldn't use Butterworth but FIRWindow with a Hamming window; mirroring the firf…

Hi, thanks for your very useful code. I found that the gain of the filter is unpredictable. I'd like the gain at the center frequency to be 1, i.e., no change between input and output. But in my code…

Hi Lars,
This is a new one to me and I can't understand why it is happening.
It has to do with the frequency filtering (I have tried both the Chebychev and Butterworth; parameters used attached here…

@rxa254 suggests that the point averaging or sparse sampling of minute or second trends are likely not good for the low-frequency comparison we want to make with IFO noise breathing and auxiliary chan…
