Radio is the technology of using radio waves to carry information, such as sound,
.... An audio signal (top) may be carried by an AM or FM radio wave. Amplitude ...
In FM, a radio wave known as the "carrier" or "carrier wave" is modulated in
frequency by the signal that is to be transmitted. The amplitude and phase remain
Radio communication is typically in the form of AM radio or FM Radio ...
frequencies which are produced by superposition of some signal upon the carrier
Nov 29, 2016 ... Artwork: How radio waves travel from a transmitter to a receiver. ... Frequency
modulation is how FM radio is broadcast; amplitude modulation is ...
May 28, 2013 ... Note in the tan area at the left of the illustration below that AM radio waves are of
a lower frequency than either FM radio or TV waves. Thus, as ...
AM and FM use different modulation techniques. AM modulates the carrier by
changing the .... FM signals usually drop of at around 50 miles from the station,
but AM waves can be refracted in the atmosphere resulting in greater range.
Mar 27, 2007 ... Radio waves have the longest wavelengths in the electromagnetic spectrum. ...
These waves are much smaller that TV and FM radio waves.
Sep 6, 2016 ... AM involves the alteration of the amplitude of the carrier wave, whereas FM
involves changes in the frequency of the carrier wave.
