Modulation reduces the size of the antenna and attracts low attention. Some modulation techniques for mobile radio are: Frequency modulation (FM): A popular analog modulation technique used in mobile communications systems. In FM, the amplitude of the modulating carrier is kept constant while its frequency is varied by the modulating message signal. Amplitude modulation (AM): A modulation technique that is used in electronic communication. It is most commonly used for transmitting messages with a radio carrier wave. Quadrature amplitude modulation (QAM): A form of modulation widely used... Show more Modulation reduces the size of the antenna and attracts low attention.
