Hi, I would like to know whether the source code of the Spectrum function can be shared or if not I would like to know what does this part means

"Spectral analysis; returns the relative amplitude of the spectral component given"


I know that in electrical engineering for instance there are spectrums that give in the x axis the frequency and in the y axis the amplitude or "energy" of the wave (light, sound) but here I would like to know if this amplitude is measured in PIPs or Lots or units of the account currency or what so that I can derive better algorithms.

Thanks beforehand!
