Preface of Electronic Communication Systems Fourth Edition By Louis E. Frenzel Jr book:
This new fourth edition of Principles of Electronic Communication Systems is fully revised and updated to make it one of the most current textbooks available on wireless, networking, and other communications technologies.
Because the field of electronic communications changes so fast, it is a never-ending challenge to keep a textbook up to date.
Electronic Communication Systems Fourth Edition.
While principles do not change, their emphasis and relevance do as technology evolves.
Furthermore, students need not only a i rm grounding in
the fundamentals but also an essential understanding of the real world components, circuits, equipment, and systems in everyday use.
This latest edition attempts to balance the principles with an overview of the latest techniques.
A continuing goal of this latest revision is to increase the
emphasis on the system level understanding of wireless, networking, and other communications technologies.
Because of the heavy integration of communications
circuits today, the engineer and the technician now work more with printed circuit boards, modules, plug-in cards, and equipment rather than component level circuits.

As a result, older obsolete circuits have been removed from this
text and replaced with more integrated circuits and block diagram level analysis.
Modern communications engineers and technicians work with specifications and standards and spend their time testing, measuring, installing, and troubleshooting. This edition moves in that direction.
Detailed circuit analysis is still included in selected areas where it
proves useful in understanding the concepts and issues in current equipment.
In the past, a course in communications was considered an option in many electronic programs. Today, communications is the largest sector of the electronics field with the most employees and the largest equipment sales annually.
In addition, wireless, networking, or other communications technologies are now contained in almost every electronic product.
This makes a knowledge and understanding of communication a must rather than an option for every student.
Without at least one
course in communications, the student
may graduate with an incomplete view of the products and systems so common today.
This book can provide the background to meet the needs of such a general course.
As the Communications Editor for Electronic Design Magazine (Penton),
I have observed the continuous changes in the components, circuits, equipment, systems, and applications of modern communications.
As I research the field, interview engineers and executives, and
attend the many conferences for the articles and columns I write, I have come to see the growing importance of communications in all of our lives.
I have tried to bring that perspective to this latest edition where the most recent techniques and technologies are explained.
That perspective coupled with the feedback and insight
from some of you who teach this subject has resulted in a textbook that is better than ever.
