In 1938, the director of the Signal Corps Laboratories at Fort Monmouth, New Jersey, Col. Roger B. Colton, transformed ...

Frequency Modulation (FM) sounds simple at first, but understanding the electronics behind modulation and demodulation of an FM signal can be confusing. We’ve covered the basics before ...

Frequency Modulation (or FM) synthesis is a simple and powerful method for creating and controlling complex spectra, introduced by John Chowning of Stanford University around 1973. In its simplest ...

Pulse counting works by generating a narrow, fixed-width square wave pulse at a set point in the received FM signal’s waveform, usually at the zero-crossing point. Since the frequency of the ...

Edwin Howard Armstrong (1890-1954), the inventor of the "Regeneration" and "Superheterodyne" circuits as well as "Frequency Modulation," or FM. A flamboyant man with a fondness for fast cars and a ...

When did FM radio become more popular than AM radio? "FM" broadcasting, invented in the early 1930s, uses frequency modulation, offering better sound quality than AM. Although it was clearer than ...

Saelig Company, Inc. has introduced the Siglent SSG6082A-V Vector Signal Generator, which provides an output frequency range from 9 kHz to 8 GHz, with AM, FM, and PM analog modulation as well as pulse ...

FM, which stands for Frequency Modulation, is one of the radio broadcasting systems in the UK. FM uses frequencies from 87.5 MHz to 108MHz. The BBC broadcasts a number of UK-wide network ...

It was superseded by MFM and RLL. FM radio was invented in the early 1930s by Edwin Howard Armstrong, who years earlier had made a fortune selling RCA his amplifier technology. When he asked RCA ...
