What is amplitude modulation / Frequency Modulation?

Question

Accepted Answer

Amplitude modulation (AM) and frequency modulation (FM) are techniques used in telecommunications to transmit information.

Amplitude modulation (AM) is a modulation technique where the amplitude of the carrier signal is varied in proportion to the waveform being transmitted.
Frequency modulation (FM) is a modulation technique where the frequency of the carrier signal is varied in proportion to the waveform being transmitted.
AM is commonly used in broadcasting, such as AM radio stations.
FM is commonly used in broadcasting, such as FM radio stations.
AM is more susceptible to noise interference compared to FM.
FM provides better sound quality and is less affected by noise.
AM is simpler to implement and requires less bandwidth compared to FM.
FM allows for the transmission of stereo audio signals.
Both AM and FM are used in various communication systems, including television and mobile networks.
