This book is beyond bad. The notation is by far the worst. I have never seen such a messy way of describing domains and ranges or signals as what is used in this book. It honestly doesn't even make sense to me or anyone else I know that's seen this book.



The examples are impossible to follow due to the notation that is used and it simply adds more frustration to anyone trying to learn signals and systems. I guess you can tell my main problem is with this ridiculous notation but the book also just fails to be a learning tool. Most of the time you spend trying to figure out what the author was trying to say rather than learning about signals and systems.



If you're a student and this book is required for your class, try to do without it and find something else, because this book sure won't help.
