Frequency Modulation Summary
459 words, approx. 2 pages The invention of frequency modulation (FM) was a great improvement over amplitude modulation (AM) radio. Reginald Aubrey Fessenden made the world's first AM radio broadcast in 1906. With amplitude modulation, the amplitude (the distance between the...

Frequency Modulation : Environmental Health Terms
35 words, approx. 1 pages One of the principal means of encoding a radio signal to transmit audio or visual images, differentiation being achieved by variations in the frequency, the amplitude remaining the same. See also: AMPLITUDE...

Frequency modulation Information
1,791 words, approx. 6 pages
 In telecommunications, frequency modulation (FM) conveys information over a carrier wave by varying its frequency (contrast this with amplitude modulation, in which the amplitude of the carrier is varied while its frequency remains constant). In analog...

Modulation methods--frequency modulation. (All About).
01/01/2003: 2,848 words, approx. 10 pages The use of frequency modulation (called FM) is another method of adding intelligence to a carrier signal. While simple on-off keying (as used in Morse Code) and amplitude modulation were the first methods used to modulate a carrier, the use of FM had...

Current amp provides frequency modulation.
12/04/1997: 558 words, approx. 2 pages Current feed-back operational amplifiers are introduced in VHF-band RF applications. Bipolar transistors and field-effect transistors are replaced in high-frequency circuits, which are basically voltage-controlled oscillators (VCO) that display minimum modulation for a wide range of frequency. This design technique consists of an eight-pin integrated...
