Linear and Time Invariant Systems

Based on the book $\text{Signal Representation}$, it is described how to mathematically capture the influence of a filter on deterministic signals.

• The book defines distortions and describes the Laplace transform for causal systems as well as the properties of electric leads.
• The filter influence on a random signal is covered later in Chapter 5 of the book $\text{Theory of Stochastic Signals}$ .

The subject matter corresponds to a  $\text{lecture with two semester hours per week (SWS) and another SWS of exercises}$.

First of all, here is an overview of the contents based on the  $\text{four main chapters}$  with a total of  $\text{twelve individual chapters}$.
