## What You’ll Find In This zyBook:

### More action with less text.

• The NI Engineering Signals and Systems texts gets a new, interactive version as a zyBooks title for 2020.
• Applications of signals and systems for engineering are presented alongside concepts and mathematical models.
• Practice problems with fixed parameters allow students to practice more advanced problems and see different examples.
• Auto-graded challenge activities also help students practice solving problems with variables and increasing difficulty levels. Includes labs that encourage students to vary parameter values to clarify many of the examples and associated problem-solving assignments.

“Out of all the online materials and physical texts I have used, zyBooks is the best thing I have ever used. It’s so concise and to the point and easy to understand.”
