Hi All,

I have a very annoying problem and hoping anyone would have a solution for me. I have acceleration data collected from an accelerometer at 2500 Hz. We are interested in obtaining displacement data. I tried integrating the data twice but I end up with a mess. I know that there is a special way for doing that but I do not know how you would it.

I attached a copy of my acceleration and displacement graphs as well as the actual data (acceleration being in the A column and displacement in the B column).

Thanks in advance!
