Amplitude Modulation (Noun)
Meaning
Modulation of the amplitude of the (radio) carrier wave.
Classification
Nouns denoting communicative processes and contents.
Examples
- The amplitude modulation technique is used to encode information onto a radio wave by varying the amplitude of the carrier wave.
- The radio station broadcast music using amplitude modulation, allowing listeners to tune in with their AM radios.
- In the early days of radio, amplitude modulation was used for broadcasting because it was simpler and more reliable than frequency modulation.
- Amplitude modulation is less resistant to noise and interference compared to frequency modulation or phase modulation.
- The process of amplitude modulation involves multiplying the carrier wave with the information signal to produce a modulated wave.
