How Do I Double Integrate Discrete Acceleration Data to Find Displacement?

[sanjayindia]

I understand that I need to double integrate to convert acceleration signal to displacement signal. If I have an acceleration signal at discreet times (no algebraic realtion to relate accelration to displacement), how do I double integrate? In other words i just have 2 colums, one with time and the other with acceleration. How do I double integrate? Please advice

Can you, from the two existing columns, generate a third column that lists "instantaneous" velocities at those times ? Once you do that, repeat the algorithm to generate displacements for each interval. From these last numbers, you should be able to find the total displacement.
