Report filter roll off characteristics

1

Hi brainstorm experts,

I want to report the dB/octave slope of the bandpass filter I used (bandpass 3 - 55Hz). When I click on view filter response (see the screenshot below), I saw the numbers for low transition and high transition, but I don't see anything plotted in the frequency response. So where can I find out the Roll off characteristics?(e.g., on the low end, what are the frequencies where 100% activity is removed and 100% is passed? and likewise for the high end?)

Thanks!
Yuhan

Please start by updating Brainstorm, what you show here is not the current version of the filter process, you have some options missing.
