AM Radio Transmitter
An AM radio transmitter is a device that sends audio signals, like music or voice, over long distances using amplitude modulation. It works by mixing the audio signal with a high-frequency carrier wave, changing the wave's strength (amplitude) to encode the sound. This modulated wave is then amplified and transmitted through an antenna as radio waves. These waves travel through the air and can be received by AM radios, which decode the amplitude changes to reproduce the original audio. AM transmitters are fundamental to broadcast radio, providing accessible communication over large areas.
