AM Broadcasting
AM broadcasting refers to transmitting radio signals using amplitude modulation, where the strength (amplitude) of the carrier wave varies in line with the audio signal. This method allows radio stations to send sound over long distances, especially at lower frequencies. AM radio is widely used for news, talk shows, and music, providing broad coverage area. Despite some susceptibility to noise and interference, AM remains a reliable technology for radio broadcasting, especially in rural and remote regions. It operates primarily in the medium wave band and has been a foundational form of radio communication since the early 20th century.
