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 ...

THE manner in which this book has been written enables any one of the subjects mentioned in the title to studied alone ; but there are sufficient cross-referenced to indicate the relationships ...

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 ...

Amplitude modulation (AM) is also widely used to alter a carrier wave to transmit data. For example, in AM radio, the voltage (amplitude) of a carrier with a fixed center frequency (the station's ...

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 ...

It was superseded by MFM and RLL.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 ...
