What is FM deviation?
Frequency deviation ( ) is used in FM radio to describe the maximum difference between an FM modulated frequency and the nominal carrier frequency. The term is sometimes mistakenly used as synonymous with frequency drift, which is an unintended offset of an oscillator from its nominal frequency.Click to see full answer.

Hereof, what is deviation ratio in FM?The deviation ratio in FM can be defined as: the ratio of the maximum carrier frequency deviation to the highest audio modulating frequency. m = Max frequency deviation/Max modulation frequency.Also Know, what does FM in FM radio stand for? FM stands for “Frequency Modulation,” and, unlike AM radio, sound is transmitted through changes in frequency. While both FM and AM radio signals experience frequent changes in amplitude, they are far less noticeable on FM. Also to know is, how does a FM radio work? FM Radio Broadcasts FM radio uses frequency modulation. When the frequency is modulated between low and high, music or voice is being transmitted by the carrier frequency. But only the frequency changes as a result; the amplitude remains constant the entire time.Which is better AM or FM?In AM, a radio wave known as the “carrier” or “carrier wave” is modulated in amplitude by the signal that is to be transmitted. FM is less prone to interference than AM. However, FM signals are impacted by physical barriers. FM has better sound quality due to higher bandwidth.
