what is AM and FM?

Accepted Answer

AM and FM are two types of modulation techniques used in radio broadcasting.

AM stands for Amplitude Modulation, where the amplitude of the carrier wave is varied to transmit information.
FM stands for Frequency Modulation, where the frequency of the carrier wave is varied to transmit information.
AM is commonly used for broadcasting in the medium wave and long wave bands.
FM is commonly used for broadcasting in the VHF (Very High Frequency) band.
AM signals are more susceptible to noise and interference compared to FM signals.
FM signals provide better sound quality and are less affected by noise.
