Description

Newnes Telecommunications Pocket Book discusses the equipment, systems, and techniques used in the telecommunications network. The book is comprised of 25 chapters that are organized into four parts. The first part covers components of particular relevance to telecommunications. The second part deals with commonly used circuit assemblies such as filters, attenuators, modems, and digitizers. The third part discusses organization and standards. The last part talks about telecommunications network practice, including analogue and digital, fixed and mobile systems. This text will be of great use to professionals in the telecommunications industry.
