520			_aThis comprehensive introduction to electronic communications explores the fundamental concepts -- and their state-of-the-art application in radio, telephone, facsimile, television, satellite, and fiber optic communications. It features an explanatory as well as descriptive approach, avoids lengthy mathematical derivations, and introduces the use of Mathcad for problem solving in selected areas. The major additions to the fourth edition are new chapters on digital signals and digital communications. Many of the other chapters have been considerably expanded, and new problem sets have been added. Mathcad1 has been introduced as a tool for problem solving, but the problems are formulated in such a way that these can be solved using other computer packages, or a good calculator.
