I am a student of computer science (not the university but technical school). I am interested in the world of DSP, and I saw that it is closely connected with mathematics. I noticed for example that a lot is based upon the Fourier I'm slowly trying to learn.
I also want to buy the book "Understanding Digital Signal Processing", but I do not know what I would go against it, and if I can understand it. What I want to know is a short list of topics needed before we can deal with such a study that one should know, is listed for reference material.
Let me give you an example of what I mean (to be taken only indicative, since we do not know almost nothing of DSP)
Science: Anatomy of the human ear, Anatomy of the human eye.
I know most of you are engineers with years of work experience and master behind it, but somewhere we must also begin ;)
