Communications 101 Textbook

This is a partially-completed textbook on elementary communications. It covers both analog and digital techniques, and is written in a (hopefully) simple style which should be easy reading for most students, from a high school level up through college.

NOTES:

1. This text is copyright (C) 1998 - 2006 by Peter A. Stark, and All Rights are Reserved.
2. You may read and study this material, print it out for your own use, or (if you are an instructor in the Verizon Next Step program) you may also give copies to your students and use it as a text. Other than that, you may not distribute it or in any way violate our copyrights. The publication of this material on this site does not release it into the public domain.
3. Although the latest Telcom I outline puts digital circuits somewhere between chapters 3 and 4, I'm not quite happy with the resulting flow of material, so I have put it into Appendix C instead. Feel free to cover it whenever you'd like.
4. I will add review problems and questions as I get to them.
5. Any comments, suggestions, and corrections will be appreciated. There are many places where I have kept things intentionally short and to the point. If you have any additions, or topics you feel should be covered, please let me know. My email address is stark-at-cloud9-dot-net (deliberately obfuscated to try to minimize spam ... sorry.)
