Revision as of 11:38, 15 June 2021

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 $\text{Linear and Time-Invariant Systems}$ .


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

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:

$(2)$    $\text{General notes about the book}$   (authors,  other participants,  materials as a starting point for the book,  list of sources)
