Theory of Stochastic Signals

This third book of our learning tutorial deals in detail with stochastic signals and their modeling.

• Knowledge of  $\text{stochastic signal theory}$  is an important prerequisite for understanding the following books, which focus on transmission aspects.
• Knowledge of the first two  $\text{LNTwww}$ books, which include the representation of $\text{ deterministic signals}$  and the description of  $\text{LTI systems}$   ⇒   "linear and time-invariant systems"  is helpful for understanding this book,  but not required.

The course material corresponds to a  $\text{lecture with three semester hours per week (SWS) and two SWS exercises}$.

Here is a table of contents based on the  $\text{five main chapters}$  with a total of  $\text{28 individual chapters}$.
