AM broadcasting is radio broadcasting using amplitude modulation transmissions. It was the first method developed for making audio radio transmissions, and is still used worldwide, primarily for medium wave transmissions, but also on the longwave and shortwave radio bands.

What does AM mean in frequency?

AM and FM modulated signals for radio. AM (Amplitude Modulation) and FM (Frequency Modulation) are types of modulation (coding). The electrical signal from program material, usually coming from a studio, is mixed with a carrier wave of a specific frequency, then broadcast.

What is FM and AM radio frequencies?

Frequency range. AM radio ranges from 535 to 1700 kHz or up to 1200 bits per second. FM radio ranges in a higher spectrum from 88.1 to 108.1MHz. or up to 1200 to 2400 bits per second.
