I know this has been asked many times.
I am integrating acceleration data from MEMS accelerometer to get velocity. I found an app note by freescale  http://cache.freescale.com/files/sen...ote/AN3397.pdf It ignores the sampling time to calculate the area. The formula should be sample: Vx= V(x1)+[N(N1) * T]. Right? But the app note it is  Vx = V(x1)+N+[((N(N1))/2] V(x1) is the previous integration result.
