For AM (amplitude modulation) the transmitted carrier`s amplitude is forced to vary in proportion to the amplitude of the intelligence that you wish to transmit. Where as for FM (frequency modulation) the transmitted carrier`s frequency is forced to vary in proportion to the amplitude of the intelligence that you wish to transmit. Detectors in the receivers are used to recover the intelligence. AM systems are much more susceptible to random noise caused primarily by severe weather and low signal strength at the receiver. FM systems are pretty much immune to noise because FM detectors do not respond to amplitude variations in the carriers. However FM transmitters requires a wider frequency bandwidth for transmission than does AM transmitters. Standard television transmitters use two carriers per channel. The sound carrier is frequency modulated and the picture carrier is amplitude modulated. The tv receiver is designed to receive both carriers. It also has two separate detectors, one for sound and one for picture. The picture information is routed to the picture picture tube and the sound is routed to the speaker(s).

What is FM transmitter and what are the different FM transmitters?
FM transmitter : In this case the frequency of a carrier signal is modulated/altered in accordance with that of frequency of modulating signal. TYPES OF FM TRANSMITTER: 1> directly modulated FM transmitter. 2>indirectly modulated FM transmitter. an FM transmitter is a portable device that plugs into the headphone jack or proprietary output port of a portable audio or video device, such as a portable media player, CD player, or satellite radio system. The sound is then broadcast through the transmitter, and plays through an FM broadcast band frequency. Purposes for an FM transmitter include playing music from a device through a car stereo, or any radio.
