Very good introduction to the subject. I am a EE working in the RF and data communictions fields and still refer back to it every so often. Lots of narrative. Maybe a little dated now in some areas, but there are other books for this. What this book does is clearly explain basics like data coding, modulation, data links, etc., etc. I find that moving to the more advanced books is easier after you nail down the concepts with a book like this.
Yes, 5 stars, but it depends on what you're looking for. This is a very good intro to Electronics concepts and systems. It doesn't go into great technical detail, but I find I understand a topic better if I read a book like this first, then progress on to more sophisticated treatments. It gives you a high-level understanding of the topic and keeps you from getting bogged down in the weeds. There are a lot of pages, but it's a quick read. If you're fairly new to amplifiers, oscillators, transmitters, receivers, etc., go thru this first, then select something like "Art of Electronics" for the follow-up.
