Originally published in 2004, this book provides a detailed introduction to radio frequency (RF) engineering, using a straightforward and easily understood approach combined with numerous worked examples, illustrations and homework problems. The author focuses on minimising the mathematics needed to grasp the subject while providing a solid theoretical foundation for the student. Emphasis is also placed on the practical aspects of radio engineering. The book provides a broad coverage of RF systems, circuit design, antennas, propagation and digital techniques. It will provide an excellent introduction to the subject for graduate students, researchers and practising engineers.

In 1775 Cherokee leaders sold most of Tennessee and Kentucky to the recently arrived white settlers, but Dragging Canoe, a proud chief, said that the sacred land should not be defiled by the white man's ax and plow. "This is the Dark and Bloody Ground!" he proclaimed to the assembled chiefs.Perhaps it is the abundance of decaying mansions that harbor dark and sinister secrets, or perhaps it is Tennessee's tragic heritage of war and defeat, or it may just be the love of a good story that accounts for the fact that Tennessee is steeped in strange tales. Each of these 40 accounts has been exhaustively researched and is presented as accurately as possible, inclulding:The day in 1877 when it rained foot-long snakes in MemphisThe arch rivals who are buried in the state capitol building; on quiet nights one can still hear them arguingElvis's ghost, who visits Graceland in the early morning in his black limousineThe mathematics professor from the University of Nashville who suddenly burst into flamesAndrew Jackson's encounter with the infamous Bell WitchThe vampire found in Bradley County, with a wooden stake through her heartThe day a UFO buzzed Huntsville, Chattanooga, and Knoxville
