Normalized frequency unit
Web17 de jul. de 2024 · x ( t) = 5 c o s ( 2 π f 0 t) This produces a two-sided spectrum peak at f 0 with a peak amplitude of 2.5. However, that's not the result of the exact fourier transform, which should be: X ( f) = 2.5 ( δ ( f − f c) + δ ( f + f c)) That is, I expect the amplitude to increase as the frequency bin shrinks (with the total area remaining at 2.5). Web6. It depends what you mean by "normalised"; it also depends on your software's choices. "Normalised" is a word often avoided by statistical people, because it is ambiguous as between (a) scaled or standardized (e.g. to total 1 or to mean 0 and SD 1) and (b) transformed (approximately) to normality, meaning normal or Gaussian distribution.
