FFT units
Hi José.
a.u. - arbitrary units. It is when you do not know well units of the original signal. For example for sound when the microphone is not calibrated. When we know the original signal we may use corresponding units. For example for the accelerometer the unit is m/s², so FFT spectrum should have unit m/s² * s = m/s ...
a.u. nevertheless is always valid :o)
