In telecommunications and signal processing, frequency modulation (FM) is the encoding of information in a carrier wave by varying the instantaneous frequency of the wave.
The early history of radio is the history of technology that produces and uses radio instruments that use radio waves. Within the timeline of radio, many people contributed theory and inventions in what became radio. Radio development began as "wireless telegraphy". Later radio history increasingly involves matters of broadcasting.
In telecommunication systems, Carrier frequency is a technical term used to indicate:
Medium wave (MW) is the part of the medium frequency (MF) radio band used mainly for AM radio broadcasting. For Europe the MW band ranges from 526.5 kHz to 1606.5 kHz, using channels spaced every 9 kHz, and in North America an extended MW broadcast band ranges from 525 kHz to 1705 kHz, using 10 kHz spaced channels. The term is a historic one, dating from the early 20th century, when the radio spectrum was divided on the basis of the wavelength of the waves into long wave (LW), medium wave, and short wave (SW) radio bands.
AM broadcasting is a radio broadcasting technology, which employs amplitude modulation (AM) transmissions. It was the first method developed for making audio radio transmissions, and is still used worldwide, primarily for medium wave transmissions, but also on the longwave and shortwave radio bands.
In telecommunications, a carrier wave, carrier signal, or just carrier, is a waveform that is modulated (modified) with an input signal for the purpose of conveying information. This carrier wave usually has a much higher frequency than the input signal does. The purpose of the carrier is usually either to transmit the information through space as an electromagnetic wave, or to allow several carriers at different frequencies to share a common physical transmission medium by frequency division multiplexing. The term is also used for an unmodulated emission in the absence of any modulating signal.
Radio broadcasting is transmission by radio waves intended to reach a wide audience. Stations can be linked in radio networks to broadcast a common radio format, either in broadcast syndication or simulcast or both. The signal types can be either analog audio or digital audio.
A subcarrier is a sideband of a radio frequency carrier wave, which is modulated to send additional information. Examples include the provision of colour in a black and white television system or the provision of stereo in a monophonic radio broadcast. There is no physical difference between a carrier and a subcarrier; the "sub" implies that it has been derived from a carrier, which has been amplitude modulated by a steady signal and has a constant frequency relation to it.
Sir Jagadish Chandra Bose (;, IPA: [dʒɔɡodiʃ tʃɔndro bosu]; 30 November 1858 – 23 November 1937), also spelled Jagdish and Jagadis, was a polymath, physicist, biologist, biophysicist, botanist and archaeologist, and an early writer of science fiction from India. He pioneered the investigation of radio and microwave optics, made significant contributions to plant science, and laid the foundations of experimental science in the Indian subcontinent. IEEE named him one of the fathers of radio science. Bose is considered the father of Bengali science fiction, and also invented the crescograph, a device for measuring the growth of plants. A crater on the moon has been named in his honour.
The Chevrolet Avalanche is a four-door, five or six passenger pickup truck sharing GM's long-wheelbase chassis used on the Chevrolet Suburban and Cadillac Escalade EXT. Breaking with a long-standing tradition, the Avalanche was not available as a GMC, but only as a Chevrolet. Production of the Avalanche started in September 2001 and ended April 2013; producing two generations in its lifespan.
Bose Corporation is a privately held American corporation, based in Framingham, Massachusetts, that designs, develops and sells audio equipment. Founded in 1964 by Amar Bose, the company sells its products throughout the world. According to the company annual report in the 2017 financial year, Bose received revenue of US$3.8 billion and employed more than 8,000 people. Bose is best known for its home audio systems and speakers, noise cancelling headphones, professional audio systems and automobile sound systems. The company has also conducted research into suspension technologies for cars and heavy-duty trucks and into the subject of cold fusion. Bose has a reputation for being particularly protective of its patents, trademarks, and brands.
FM broadcasting is a method of radio broadcasting using frequency modulation (FM) technology. Invented in 1933 by American engineer Edwin Armstrong, wide-band FM is used worldwide to provide high-fidelity sound over broadcast radio. FM broadcasting is capable of better sound quality than AM broadcasting, the chief competing radio broadcasting technology, so it is used for most music broadcasts. Theoretically wideband AM can offer equally good sound quality, provided the reception conditions are ideal. FM radio stations use the VHF frequencies. The term "FM band" describes the frequency band in a given country which is dedicated to FM broadcasting.
The cassette adapter allows another source of music to be played through sound systems with a tape player. This is useful for vehicles without auxiliary (aux) ports or CD players.
CFSX is an AM radio station in Stephenville, Newfoundland and Labrador, Canada, broadcasting at 870 kHz. Originally launched as a repeater on November 13, 1964, it opened its own studios in 1970. The station is owned by Stingray Digital Group Inc. It is an affiliate of VOCM.
KFNN (1510 kHz) is a commercial business news formatted radio station licensed to Mesa, Arizona, broadcasting from studios located in North Scottsdale, Arizona, on 1510 AM, and simulcast on 105.3 FM. KFNN is owned by CRC Broadcasting Company, Inc., headed by Ronald Cohen and Brian DuBose, which also owns KPSF and KXPS, both located in the Palm Springs, California area, and a financial expo company called Financial Fest. KFNN began airing primarily nationally syndicated content, and now has an extensive lineup of local and national money related programs. They have been serving the greater Phoenix community as a business/financial station since 1988. They are distinguished as the first full-time financial format of its kind in the U.S.
Bose 2.1 home theater systems began with the Lifestyle 10 CD-based system in the early 1990s. These systems included analogue inputs, CD players and AM/FM radios. The current range includes DVD-based systems and AV receivers which are designed for use with sources and released on 28 September 2012.
Bose have produced 5.1 channel home theater systems since 1994, when the "Lifestyle 12" system was released. To the present day 2 New 2017 models: Bose Lifestyle EA78 and the Bose Cinemate 140 soundbar Combo. Over the years these systems have had built in radios, CD players, DVD players, iPod docks and systems that have no internal media, thus relying on external sources.
Tivoli Audio is an American consumer audio equipment company. It was founded in 2000 by Tom DeVesto in collaboration with Henry Kloss, who noticed a gap in the consumer audio market for a high-quality, well designed and affordable AM/FM radio.
Audi Navigation Plus is an in-car media and navigation system developed by Audi. Unlike the Audi Multi Media Interface, it can not control climate, convenience, suspension or engine settings. Audi Navigation Plus units were available mostly as an optional equipment instead of standard stereo systems.
