Which came first AM or FM?
This type of transmission is called amplitude modulation (AM). It appears to have first been thought of by John Stone Stone in 1892. Many years after Armstrong’s invention of the super heterodyne, he solved radio’s last major problem, static, by inventing frequency modulation (FM), which he successfully tested in 1933.

How is FM radio transmitted?
Both AM and FM radio programs are transmitted over the air via radio waves, which are part of a range of electromagnetic waves that include gamma rays, x-rays, ultraviolet rays, visible light, infrared, and microwave. Electromagnetic waves are all around, everywhere, at different frequencies.
Why is radio frequency used?
Radio frequencies are used in communication devices such as transmitters, receivers, computers, televisions, and mobile phones, to name a few. Radio frequencies are also applied in carrier current systems including telephony and control circuits.
Who invented am?
Reginald A. Fessenden
Reginald A. Fessenden. Reginald Fessenden is known for discovering amplitude modulation (AM) radio and explaining its scientific principles. With his heterodyne principle, he put into practice the idea of mixing two high frequency signals to carry the audible low frequency of the human voice.
What was the first car with FM radio?

When was FM radio born?
FM radio was born in 1928 out of research and development as a way to successfully improve AM radio by eliminating static. With an entirely new approach to transmitting radio signals, the late Major Edwin Armstrong invented a method of producing high fidelity sound using Frequency Modulation “FM”.
