# Signal Representation

The book focuses on the mathematical description of typical signals in Communications Engineering, which can alternatively be in the time or frequency domain.

- The spectral transformations which are exclusively applicable to causal signals and systems are not treated in this book

(for example: Laplace transform, Z-transform, Hilbert transform). - Here we refer to the book "Linear and Time-Invariant Systems" .

The subject matter corresponds to a $\text{lecture with two semester hours per week (sh/w) and one additional sh/w exercise}$.

Here is a table of contents based on the $\text{five main chapters}$ with a total of $\text{19 individual chapters}$.

### Contents

In addition to these theory pages, we also offer tasks and multimedia modules on this topic, which could help to clarify the teaching material:
