Leonard R Kahn

Leonard R. Kahn (June 16, 1926 – June 3, 2012) was an electrical engineer, who invented technology for AM broadcasting. He held over 100 patents. He was primarily known for advocating several technologies designed to improve the sound quality of AM radio. His Kahn-Hazeltine system was the chief competitor to Motorola's C-Quam AM Stereo system. More than 100 stations used his stereo system before Motorola's system ultimately won out as the AM Stereo standard. Later, a part of that system was used to develop the CAM-D AM digital broadcasting technology.
