Now in full colour throughout, this edition retains the student-friendly writing style and straightforward explanations of complex concepts. This thoroughly updated guide to electronic communications covers the full spectrum of introductory topics, from AM/FM transmission and reception, through digital and data communications, to the latest information on fibre optics. The first six chapters offer a building block approach to fundamentals, providing a solid foundation that will equip students for future coursework. Subsequent chapters are written to be stand-alone units, to allow instructors to pick-and-choose coverage that fits their students needs and course objectives.
