ANGLE MODULATION NPTEL PDF

In principle, the modulating signal in both frequency and phase modulation may either be analog in nature, or it may be digital. In general, however, when using digital signals to modify the carrier wave, the method is called keying , rather than modulation. Furthermore, another digital modulation is line coding , which uses a baseband carrier, rather than a passband wave. The methods of angle modulation can provide better discrimination against interference and noise than amplitude modulation. Frequency modulation[ edit ] Frequency modulation is widely used for FM broadcasting of radio programming , and largely supplanted amplitude modulation for this purpose starting in the s, with its invention by American engineer Edwin Armstrong in Phase modulation[ edit ] Phase modulation is important in major application areas including cellular and satellite telecommunications, as well as in data networking methods, such as in some digital subscriber line systems, and WiFi.
