\subsection{Diskrete Fourier Transformation}
% NOTE: I'll do these 2 subchapters. Based on the lecture, we can leave out quite a lot here.
Lecture: 3.2.1 eigentlich nur Endergebnis wichtig. 3.2.2 viel anschaulicher und theo. Grundlage für Anwendung. 3.2.3 zeigt kurz code.
% 1/sqrt(N) ist numerisch sehr schwer, d.h. wenn möglich nie nutzen. (d.h. ist bem 3.2.8 genau so definiert)
% NOTE: script p.74 sum transformation has errors. he said he'll fix.
