Fourier tutorial: Spectra (2)

Outline

DC removal and its technical reason. Windowing and its side-effects. Epoching and its advantages. Fragmentary sines. Phase spectra.

July 2011. This tutorial project is now in abeyance. It may be revived in the future, but only if I can find some sound motivation.
