What does am and FM stand for radio?

AM and FM are the two primary frequencies used for radio broadcasting in the United States. An AM station broadcasts at about 1,000 kilohertz and an FM station at about 100 kilohertz. Both of these frequencies allow for a greater reach and louder sound.

What does an FM radio stand for?

"FM" stands for frequency modulation. When a radio broadcasts on the FM radio band, it shifts the frequency of the signal an exact number of times per second. This allows for more channels and higher quality sound. The acronym was coined because the sound of the signal varies like a musical note. The "FM" in the name does not stand for "freedom" or "music" as many people mistakenly believe.

What does AM mean in radio?

The letters AM stand for amplitude modulation. The signal from an AM radio is a varying electrical current that is either turned on or off at varying levels between the two states. This signal is then sent to a radio’s speaker, which vibrates to produce sound. These radios are incredibly common and are the oldest form of radio technology.

What is the meaning of AM radio?

Short for amplitude modulation, or amplitude modulation, is a common form of electronic transmission used in radio broadcasting. It uses amplitude variations in a carrier wave to represent the sound. This technology dates back to the early 20th century. It was the first form of radio used for broadcasting. The frequency used is in the range of between 5kHz and 1,500kHz.
