Telecommunications by Warren Hioki (1995, Hardcover)

This book is intended to provide the reader with the technical aspects and background material on telecommunications, which is still one of the fastest-growing industries in the world.

Instead, fundamental principles are emphasized in a simplified yet comprehensive and practical manner. A fundamental background in mathematics, electronics, and digital circuits is a helpful requirement to using the text. This text is of great value to undergraduates and graduates seeking to extend or renew their discipline. Furthermore, the myriad tables, figures, example problems, and telecommunication standards make it an excellent reference for faculty, students, and practitioners.
