What's a good resource(books/website) to get started on telephone line based circuits.
This looks to be an updated one of a version that I learned from many years ago:
Are you mainly wanting to learn about POTS, or about newer cellphone technology?
Just interested in POTS now. The author(Joseph Carr) is the same guy who has written the Antenna book?
If you have a recommended resource for learning about cellular technology, please mention it.
Separate names with a comma.
