Summary

This diagram image could be re-created using vector graphics as a SVG file. This has several advantages; see Commons:Media for cleanup for more information. If a SVG form of this image is available, please upload it and afterwards replace this template with {{vector version available|new image name}}.
It is recommended to name the SVG file “Amfm3-en-de.svg”—then the template Vector version available (or Vva) does not need the new image name parameter.

DescriptionAmfm3-en-de.gif	English: Animated diagram illustrating the difference between radio waves modulated by amplitude modulation and by frequency modulation. The vertical axis represents the amplitude (voltage or current) of the signals and the horizontal axis represents time. The top graph, labeled "Signal" is the modulation signal applied to the transmitter, in this simple example a sinusoidal wave. For example it could be an audio signal from a microphone. The middle graph (red) labeled "AM", is the output of an amplitude modulated radio transmitter. The magnitude (voltage or current) of the sinusoidal carrier wave varies with the modulation. The bottom graph (blue) labeled "FM", is the output of an frequency modulated (FM) radio transmitter. The frequency of the carrier wave varies with the modulation. Español: Imagen animada en la que se muestra la diferencia entre la amplitud modulada y la frecuencia modulada. Français : Image animée montrant la différence entre un signal modulé en amplitude et un signal modulé en fréquence. Italiano: Grafico animato che rappresenta l'effetto della modulazione di un segnale sinusoidale trasmesso contemporaneamente su onde modulate secondo l'ampiezza (AM) e secondo la frequenza (FM). Português: Imagem animada em que mostra-se a principal diferença entre a amplitude modulada e a freqüência modulada. Deutsch: Animiertes Diagramm, illustriert den Unterschied zwischen Frequenzmodulation (FM) und Amplitudenmodulation (AM). فارسی: نمودار متحرک تفاوت بین امواج رادیویی که به وسیله دامنه و فرکانس مدوله می شود را نمایش می دهد.
