What does the AM in AM Radio stand for?

Answer 1

Amplitude Modulation (AM) and Frequency Modulation (FM)

AM tuning changes the amplification size of the waves being received, FM tuning controls the frequency of the waves being received.

As commercial radio rose from it's early form, the AM 'band' stood for years as the only type of radio available. As technology improved, engineers discovered that they could modulate 2 channels of higher quality sound inside of one carrier frequency. The Federal Communications Commission designated from 87 MHz to 108 MHz for the new FM format. And, with this, FM radio was born.

Answer 2

Amplitude Modulation. It refers to the way that the radio waves are modified to carry the information that is used to create the sound.

Answer 3

"Amplitude Modulation"

Note: If it's a clock radio, then that label could also denote "Ante Meridian".

Answer 4

AM/FM Amplitude Modulation / Frequency Modulation AM/FM Auto-Mapping/Facilities Management

Answer 5

Am simply means amplitude modulation as a technical term,And FM means frequency modulation which is the most used today in cars.

Answer 6

Amplitude Modulation
