Hello
I very recentrly start using Diadem 2007 and I am interested to create a spectrum of an accelerogram. That is, I have the acceleration m/s2 (sample values N=11999) acquired every 0.0025s.
Using the FFT(one time signal) I choose the peak amplitude but I can understand the Y-axis results (Fourier amplitude), i mean the units! Is there is a scale being done, how could i convert them to read the same values as in the time domain.
thank you
