WebSep 28, 2024 · Definition by FCC (Federal Communications Commission): “FM is short for frequency modulation, which refers to the means of encoding the audio signal on the carrier frequency. FM full power, low power, translator, and booster stations operate in the 88 – 108 MHz band. There are many classes of radio stations. WebFM transmitter is the whole unit which takes the audio signal as an input and delivers FM modulated waves to the antenna as an output to be transmitted. FM transmitter consists of 6 main stages. They are illustrated in the following figure. The working of FM transmitter can be explained as follows.
WebThe maximum effective radiated power permitted for any translator station is 250 watts, while the maximum effective radiated power for a booster station is 20% of the main station's maximum class power. Translator stations simultaneously rebroadcast the signal of a primary AM or FM station on a different frequency. Frequency modulation (FM) is the encoding of information in a carrier wave by varying the instantaneous frequency of the wave. The technology is used in telecommunications, radio broadcasting, signal processing, and computing. In analog frequency modulation, such as radio broadcasting, of an audio … See more If the information to be transmitted (i.e., the baseband signal) is $${\displaystyle x_{m}(t)}$$ and the sinusoidal carrier is $${\displaystyle x_{c}(t)=A_{c}\cos(2\pi f_{c}t)\,}$$, where fc is the carrier's base frequency, and Ac … See more FM provides improved signal-to-noise ratio (SNR), as compared for example with AM.
