I'm trying to filter out the noise in a displacement response. I typically do a 0-50 Hz filter to get rid of all the noise. This gets rid of some 60 Hz shit as well as some other noise past 100 Hz. The problem is with this project, I need to differentiate the response to get velocity and when I do so, all that small amplitude noise looks way worse.
Do I filter it before I differentiate and after? Just after? Just before? If I differentiate after, I can't use the 0-50 Hz range because the frequency domain looks much different. Any advice would be very helpful.
Sample rate is normally 1024 Hz by the way.
