Dear fieldtrippers,

I would like to know if someone could answer my question.
In the analysis of ERPs I use some preprocessing steps to improve the
signal-to-noise ratio; down-sampling (from 2000 to 500 Hz) and filtering
(between 1-30 Hz).
What should I do first; down-sampling or filtering, or doesn't it make
any difference?
