Full Form of FM

FM stands for frequency modulation, also called frequency-modulated electromagnetic waves. Widely used for FM broadcasting and various other wireless communication applications. In telecommunications, frequency modulation is a technique for transmitting information using a carrier wave. The carrier frequency varies according to the amplitude and polarity of the input signal. Check here Free Current Affairs Magazine DOWNLOAD NOW  

History and related information

FM broadcasting technology was invented by Edwin Howard Armstrong in the early 1930s. A radio wave is known as a carrier wave, but the phase and amplitude-phase remains the same Including wider bandwidth and improved sound quality. The frequency range of FM lies in the high spectrum from 88 to 108 MHz. It creates less noise.  In addition, you can also check out our free General Awareness E-book- Download now for all competitive exams.

What is the use of FM?

FM is most commonly used in broadcasting. FM offers great advantages in radio transmission due to its high signal-to-noise ratio. This means that radio frequency interference is minimal. This is the main reason why many radio stations use FM to radio their music.

What are the common applications of FM?

Common applications of FM

  • FM radio uses a modulation index (m>1) called wideband FM.
  • Television audio: In terrestrial television broadcasting, video signals are transmitted on AM and audio signals on FM. Helps reduce interference between video and audio signals.
  • Satellite TV: Some TV broadcasts use VHF to carry analog video signals. It helps in getting an acceptable signal at the receiving end.

What are the limitations of FM?

Machines are expensive and have a wide range. Reception is a small FM signal. For optimum interaction, the antenna should be placed close to the FM system.

Who invented the FM?

FM broadcasting technology was invented by Edwin Howard Armstrong in the early 1930s.
