Hello,
My question is about units after applying an fft. I am going from gravity units (g.u. or m/s^2). What will the units be after converting to the wavelength domain and taking an absolute value?
ftgrav = fft(data); absdata = abs(data);
23 coefficients total. Sample interval is 0.2km, therefore 5 samples per km. N/2 = 2.5km^-1
wavenum = 0 : 0.1087 : 2.51 ; plot (wavenum,absdata(1:24));
so wavenumber (km^-1) on the x and unsure about the y.
Any help would be appreciated!
