What is the full form of FM
FM: Frequency Modulation
FM stands for Frequency Modulation. It is also called Frequency Modulated Electromagnetic Wave. It is generally used for FM broadcasting and various other radio communication applications. In Telecommunication, Frequency Modulation is a technique of transmitting information using a carrier wave. The frequency of the carrier wave is varied according to the amplitude and polarity of the input signal. FM and AM both are used for radio broadcasting but FM is different from AM. AM stands for Amplitude Modulated Electromagnetic Wave. AM is prone to interference because the amplitude of AM signals can be altered easily. On the other hand FM is much less prone to interference because the amplitude of FM signals cannot be altered easily.
The FM broadcasting technology was invented by Edwin Howard Armstrong. It was invented in the early 1930's.
