WebMay 31, 2024 · Fourier Transform changes basis from time (spatial data) to frequency. To encode frequency we need amplitude (magnitude) to know how strong is signal at given frequency and phase to know when sine started - in what moment of its phase we are now. Example: take input signal $5\sin(x + \pi)$, here phase is $\pi$ and magnitude is $5$. greenville twitter codes

WebProperties of the DTFT Like its continuous-time counterpart, the DTFT has several very useful properties. These are listed in any text on signals and systems. We will take a look at a couple of them. First of all, the DTFT is linear: if x1[n] ↔ X1(Ω) and x2[n] ↔ X2(Ω), then c1x1[n]+ c2x2[n] ↔ c1X1(Ω) +c2X2(Ω) for any two constants c1,c2.
