The Mathematical Radio - Inside the Magic of AM, FM, and Single-Sideband

How a modern radio works, told through mathematics, history, and selected puzzles

The modern radio is a wonder, and behind that magic is mathematics. In The Mathematical Radio, Paul Nahin explains how radios work, deploying mathematics and historical discussion, accompanied by a steady stream of intriguing puzzles for math buffs to ponder. Beginning with oscillators and circuits, moving on to AM, FM, and single-sideband radio. Nahin focuses on the elegant mathematics underlying radio technology rather than the engineering. He explores and explains more than a century of key developments, placing them in historical and technological context.

Nahin, a prolific author of books on math for the general reader, describes in fascinating detail the mathematical underpinnings of a technology we use daily. He explains and solves, for example, Maxwell-s equations for the electromagnetic field. Readers need only a familarity with advanced high school-level math to fo
