What is the full form of FM?

FM: Frequency Modulation

  • FM full form is Frequency Modulation. “Electromagnetic Wave” is another name for it.
  • It is largely used for broadcasting and and other types of radio communication.
  • Frequency Modulation is a method of transferring data over a carrier wave in telecommunication.
  • The carrier wave’s frequency varies depending on the amplitude and polarity of the incoming signal.
  • Radio broadcasting is done on both FM and AM, but it is different from AM.
  • Amplitude Modulated Electromagnetic Wave is an acronym for AM. Because the amplitude of AM signals may be easily changed, it is prone to interference.
  • Frequency Modulation, on the other hand, is significantly less susceptible to interference because its amplitude cannot be easily changed.


Benefits of FM broadcasting

  • Because the information in an its signal is modified by frequency variation rather than amplitude variation, it is less susceptible to noise.
  • FM radio has a wider frequency range than AM radio. It has a frequency range of 88 to 108 MHz (1200 to 2400 bits per second).
  • The larger bandwidth of it produces superior sound quality.
  • FM radio is sometimes known as High Fidelity sets because of its excellent audio quality.
  • Non-linear RF amplifiers can be used to amplify its signals in FM broadcasting.
  • It is a resistant to signal variation, making it ideal for mobile applications with continually changing signal levels.
  • Its broadcasting, modulation can be used on the transmitter’s low-power stage.

Common Applications

  • FM Radio
  • Television Sound
  • Satellite TV
