 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... summary from source:
 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...

 Poptronics Modulation methods--frequency modulation. (All About).
01/01/2003: 2,846 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 to... summary from source:
EDN Current amp provides frequency modulation.
12/04/1997: 556 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...
