FM: Frequency Modulation
FM stands for FM. it’s also called Frequency Modulated radiation. it’s generally used for FM broadcasting and various other radio communication applications. In Telecommunication, FMmay be a technique of transmitting information employing aradio radiation. The frequency of the radio radiation is varied in line with the amplitude and polarity of the signaling. FM and AM both are used for radio broadcasting but FM is different from AM. AM stands for Amplitude Modulated radiation. AM is liable to interference because the amplitude of AM signals are often altered easily. On the opposite hand FM is far less liable to interference because the amplitude of FM signals can not be altered easily.
