内容説明
For one/two-term courses in Basic Electronic Communications.
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 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.
