ELI5: Why does FM radio sound better than AM radio?
gpt
AM (Amplitude Modulation) only uses 10 kilo Hertz of band width to get the sound across. On FM, they use 100 Kilo Hertz of band width. That allows for alot more fidelity of sound. The reason is how much of the spectrum is alloted for each band. AM band is .5 Megahertz to 1.7 Megahertz. But FM band is 88 Megahertz to 108 Megahertz.
