AM Demodulation Techniques

AM demodulation techniques recover the original audio or information signal from amplitude-modulated radio waves. Common methods include envelope detection, where a circuit extracts the signal's varying amplitude; product detection, which mixes the radio wave with a reference signal to isolate the original signal; and synchronous detection, which uses a synchronized reference to accurately demodulate the signal. Each technique aims to accurately retrieve the original audio content while minimizing distortion and noise, ensuring clear audio reception from AM broadcasts.
