%----------// ABSTRACT \\----------%

\begin{abstract}

The Baccalaureate Thesis creates interactive course material for Signal Processing based on the experimental math assistant Isabelle/\sisac.

The content of the course material is defined together with the Signal Processing and Speech Communication Laboratory (SPSC Lab) of Graz University of Technology (TUG). The content is planned to be used in specific lectures and labs of the SPSC and thus is thoroughly concerned with underlying mathematical and physical theory.

One challenge of this thesis is, that theory is not yet mechanized in Computer Theorem Provers (CTP); so this thesis will provide preliminary definitions in so-called \emph{theories} of the CTP Isabelle and theorems without proofs.

Another callenge is the implementation of interactive courses: this is done within the educational math assistant Isabelle/\sisac, which is under development at TU Graz. The present state of \sisac{} happens to provide the {\em first} occasion for authoring by a non-member of the \sisac{} developer team. So this challenge involves  alpha-testing of the underlying ``CTP-based programming language'', because error messages are still not user-friendly and need frequent contact with \sisac-developers.

So the practical outcome of this thesis is twofold:

(1) interactive course material hopefully useful in education within the SPSC Lab and within STEOP, the introductory orientation phase at TUG, as a preview for students in Telematics on later application of math knowledge introduced in the first semester and

(2) a detailed description of technicalities in programming implemented as an interactive Isabelle/Isar theory, providing future programmers with guidelines and \sisac-developers with feedback in usability of the CTP-based program language.

This thesis is structured into a generell part describing the math fundamentals, a practical part including the work on \cal{ISAC} and finally the management part overviewing the work process.

\part{Project Fundamentals}

\section{Introduction}

The motivation to this thesis mainly takes it source from the feeling of understanding difficult signal processing tasks and the will to help others to get this feeling to.

\par Signal Processing requieres a huge range of mathematic knowledge as well as a feeling for simplification and number tricks but even though this fact, the operations themself are no higher ones. The main task is to understand. Aside this description we think of the classic math ideas and techniques, consisting of predefined formulas, notations and forumularsations we learn.

\par Mathematics mechanized in Computer Theorem Provers \emph{(CTP)} has (almost) a problem with traditional mathematical notations (predicate calculus) for axioms, definitions, lemmas, theorems as a computer programm or script is not able to interpret every greek or latin letter and every greek, latin or whatever calculations symbol. Also if we would be able to handle thehse symbols we would have a problem to interpret them correctly. In different problems, symbols and letters have different meanings and ask for different ways to get through. Exclusive from the input, also the output can be a problem. We are familar with a specified notations and style taught in university but a computer programm has no knowledge of the form probved by a professor and the maschines themselve also have not yet the possibilities to print every symbol (correct) Recent developments provide proofs in a humand readable format but according to the fact that there is no mony for good working formel editors yet, the style is one thing we have to live with.

\par This thesis tries to \empg{connect} these two worlds and is one of the first guidelines to implement problem classes in {\sisac}. For others see related works. %--01--

The major challenge of the practical part, of this thesis, is, that "`connecting the two worlds"' involves programming in a CTP-based programming language which is in a very early state of prototyping. There is no concrete experience data ready to hand.

\subsection{Mechanization of Mathematics}

todo

hughe theories of mathematics

still a hugh gap between these theories and ``real applications'' e.g. in SP

? academic engineering starts from physics (experimentation, measurement) and then proceeds to mathematical modelling --- mechanized math starts from mathematical models and (hopefully !) proceeds to match physics.

CTP Isabelle ... survey of knowledge, links to knowledge

\paragraph{\sisac}

TODO

adds an ``application'' axis (formal specifications of problems) and an ``algorithmic'' axis to the ``deductive'' axis of knowledge ... 3-dimensional universe of mathematics.

\subsection{Notes on Problems with Traditional Notation}

Due the thesis work we discorvers severell problems of traditional notations.

u[n] !!

f x =  why not f(x) ?!?!

...

terms are not full simplified in traditional notations, in isac we have to simplify them complete to check weather results are compatible or not. in e.g. the solutions of an second order linear equation is an rational in isac but in tradition we keep fractions as long as possible and as long as they are 'beautiful' (1/8, 5/16,...)
