WebDec 29, 2024 · Here is the one that works best for me: The amplitude of the Fourier Transform is a metric of spectral density. If we assume that the unit's of the original time signal x ( t) are Volts than the units of it's Fourier Transform X ( ω) will be Volts/Hertz or V / H z. Loosely speaking it's a measure of how much energy per unit of bandwidth you have. WebApr 1, 2024 · Note that for the DTFT ω is a continuous function of frequency, while in the DFT the frequency is discrete as an index k from 0 to N − 1 with a constant ω o = 2 π / N. In the DTFT the index n extends to ± ∞, even if the function x [n] is non-zero over a finite length. Adding zeros to the DFT is adding more of these zero samples, so ...
