The mathematical radio Inside the magic of AM, FM, and single-sideband

Nahin's latest book supplies thorough mathematics backing for a century's worth of AM, FM, and single-sideband radios. Coverage begins with the mathematical underpinnings of oscillators and circuits. Trigonometric relationships, calculus, and differential equations model aspects are crucial to transmitting and receiving signals. Nahin (emer., electrical engineering, Univ. of New Hampshire) also includes historical notes about the challenges that arose as radio capabilities were created or improved. He frequently refers to G. H. Hardy's persistent position that only pure mathematics is worth considering and counterattacks with statements about the intuitive inventiveness inherent in the applied mathematics behind radio capabilities. As a bonus, each chapter ends with a series of challenge problems, with hints or solutions in the back of the book. Mathematicians, especially educators who want to demonstrate the power and usefulness of their discipline, will find much to enjoy here. Electronics and radio experts may be intrigued by what lies behind the engineering aspects of their knowledge. This is not the type of book that lends itself to curling up in a comfortable chair for a few hours of mindless reading, but its challenges are worthwhile. Summing Up: Recommended. Advanced undergraduates through faculty; professionals. --Ned W. Schillow, emeritus, Lehigh Carbon Community College
