A major change with this third edition is the availability of a new laboratory manual. The Lab Manual developed for the second edition will be retained for those of you who use it. This new Laboratory & Activities Manual provides more actual hands-on hardware experiments with modern circuits and components. While many circuits are still explored, the attempt is to push toward more systems-level experiments. Building a practical, affordable but meaningful lab is one of the more difficult parts of creating a college course in communications. This new manual provides practice in the principles by using the latest components and methods. Affordable and readily available components and equipment have been used to make it easy for professors to put together a communications lab that validates and complements the text.
While I liked the textbook, this companion lab manual was clearly a low-effort job. The lab instructions are terrible and hard to follow and most of the time there's no description of the expected outcome. So, it's possible to go through an entire lab without getting anything right.
Also schematic errors. Schematic errors turned several 1 hour labs into 4 hour labs of deep, soul-sucking agony and frustration. But damn, did I feel good solving those and proving the book wrong. Then throwing it against the wall. Probably stomping on it a few times.
