well, there is a lot of different way to filter data. I think it's important to have different kind of filter.
that is why you can find an infinite impulse response filter (both lop and hip). it's name is iir.
the finite response filter is named fir
median filter are named media_3, median_5, median_n.

There is so much filter that it could not go in the [lop] or [hip] syntax.
