If your original version is more right for you then I’ll change it back monday. :)

Hmm, I see you changed the scaling into 1/sqrt(N) – I actually used the scaling factor 1/N on purpose, since it yields a nicely normalized series, to reflect my pragmatic approach as an engineer.

If you do in fact prefer your fancy symmetric ideal scaling factory, just leave it there :o)

Great, it has been added. Now start hanging them on you doors :)

Hello there.

How about the discrete Fourier transform? It’s pretty neat, and its uses are vast and numerous.

\[
F(k) = \frac{1}{N}\sum^{N-1}_{n=0}f(n) \cdot \textrm{e}^{-i 2 \pi k \frac{n}{N}},\quad k = 0, 1, \ldots, N-1
\]
