Query: Not enough examples

Okay, maybe I'm just dumb, but this book barely has any examples besides the few problems at the end of each chapter. The book is full of equations and not enough explanation. I would not recommend taking this class or buying this book. Of course, if you're an EE student at UC Davis, this class (EEC140A) is required. So, tough luck. All I can tell you is... don't slack off. Attend the lectures, and don't fall behind. I found the materials to be pretty difficult. There's no way around it. Study.
