Not G accelerations

hi, I have done by now: a 3-axis accelerometer MMA7260 read by a 12-bit Coldfire MCF52233 sampled at 500 Hz. noise filtering of vibrations do it by calculating the average value of the n-axis and then subtracting it to the n-axis. each n-axis average value is filtered by a 9 tap Hamming LP FIR. the ...
