content: This book was very hard to understand. It had sections that were poorly organized with a total disregard for extensive examples. Examples that were shown were not only short, but were unrepresentative of problems that were shown in the Problem section at the end of each chapter. I also found it extremely frustrating that the author insisted on including problems in the problem section that required him to basically add full explanations and include indepth lessons for each. The author of this book clearly overestimates the knowledge held by most beginner Signal students.
