Fourier transform (family)


Video #1: intro to the Fourier transform

Nice explanation, especially why the Fourier transform F(u) of a real valued function f(t) is complex.

Reason: F(u) encodes as a complex number

  • the magnitude of each sinoid (real part)
  • and the phase shift (imaginery part)

Video #2: intro to the Fourier transform

Very nice drawings + explanations, but the speaker speaks without any breaks!
