This 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 elcetronic. 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.
Each chapter begins with an Introduction and concludes with Problems. Self Capacitance of a Coil.
