Black Magic for Computer Scientists

Signals and deeper singal theory is still perceived as “Black Magic” by computer scientists and avoided or overshaded by confuse implementations. Jack Schaedler wanted to change this and introduced a pretty nice looking introduction to circle sines and  signals, condensend in “a compact primer on digital signal processing“. For all those people out there who ever wanted to understand how a DFT or FFT works and only heard little about the topic, this might be a good introduction to it. It is nicely designed and covers all basic topics from discrete signals, to mathematical representations up until Nyquist-theorem or Aliasing. With  embedded moving examples the theory is presented in a nice graphical way for an easy understanding.

    cool i always wanted to wrap my mind around it!
