Amplitude Modulation Theory

Amplitude Modulation (AM) is a method of transmitting signals, such as radio broadcasts, by varying the strength (amplitude) of a high-frequency carrier wave in accordance with the information signal, like music or speech. The original sound wave modulates the carrier's amplitude, creating variations that carry the essential audio information. When received, these variations are extracted and converted back into sound. AM allows effective communication over long distances, but it is more susceptible to noise and interference compared to other methods. The process relies on precise synchronization so that the receiver can accurately recover the original audio signal.
