First of all I would like to thank you very much for your help. Are there particular steps to test the potential causes? I attached an image of what Matlab gives me. On the top is the acceleration data, in the middle is the velocity, and the displacement is at the bottom. The displacement is...

Thank you very much for the reply. I apologize for not putting any graphs, I should have thought about that. I added it to the file and uploaded it to this reply. Hopefully it posts. The displacement data is captured by LVDT. The reason it doesn't start at zero is that it wasn't zeroed out...

Hi All, I have acceleration data from an accelerometer. I tried integrating it twice to calculate displacement. The problem is that its off. I am expecting about 1 cm peak to peak but instead getting about 5 cm peak to peak. The Matlab program we use transforms the signal from a time to...
