I study tremor. In Origin, I use the FFT to determine the frequency and amplitude of the tremor measured using an accelerometer. In what units of measurement is the amplitude given (meters, centimeters)? Thanks.

The same as the initial signal (I assume, acceleration). Not the same as the power density.
