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.
What do you mean by FM station?
Frequency Modulation
FM stands for Frequency Modulation, and, unlike AM radio, sound is transmitted through changes in frequency.During an FM broadcast, slight changes in amplitude go unnoticed because the audio signal is presented to the listener through changes in frequency, not amplitude.
What is the difference between AM and FM radio stations?
The difference is in how the carrier wave is modulated, or altered. With AM radio, the amplitude, or overall strength, of the signal is varied to incorporate the sound information. With FM, the frequency (the number of times each second that the current changes direction) of the carrier signal is varied.
How do you get an FM radio station?
In order to legally broadcast on FM frequency bands you have to obtain a license from the FCC. There are two types FM radio licenses: LPFM or Low Power FM (local) – These stations have a limited range and are only available to non-profit organizations.
What is the most popular FM radio station?

Which is better AM or FM?
FM has better sound quality due to higher bandwidth. AM radio ranges from 535 to 1705 KHz (OR) Up to 1200 bits per second. FM radio ranges in a higher spectrum from 88 to 108 MHz.In AM radio broadcasting, the modulating signal has bandwidth of 15kHz, and hence the bandwidth of an amplitude-modulated signal is 30kHz.
Why is FM radio better than AM?
“FM, which stands for Frequency Modulation, has better sound quality due to higher bandwidth. Also, the way the audio is encoded for FM makes it less sensitive to interference from electrical activity from storms or electrical devices than AM.
Is WiFi FM or AM?
WiFi works off of the same principal as other wireless devices – it uses radio frequencies to send signals between devices.For example your car stereo receives frequencies in Kilohertz and Megahertz range (AM and FM stations), and WiFi transmits and receives data in the Gigahertz range.
Which travels farther AM or FM?
AM broadcasts use longer wavelength radio waves than FM broadcasts.Frequency modulation allows FM waves to encode more information than does amplitude modulation, so FM broadcasts usually produce clearer sounds than AM broadcasts.
What does XM stand for radio?
XM. No Modulation (satellite radio)
How can I make my home FM radio station?
The same principles apply: use the tiny computer to create and broadcast the signal, and attach an antenna to give it the broadcast range.
- Set up your Raspberry Pi.
- Install the FM radio software.
- Choose some music.
- Add an antenna.
- Broadcast.
- Tune your radio and enjoy.
Can I broadcast radio without a license?
Regardless of popular misconceptions, it is not legal to broadcast on FM at low power, or at any power, without a license from the FCC.The section of the Federal Code of Regulations that regulates legal, unlicensed FM transmissions is Title 47, Part 15.
How far can you transmit FM legally?
What is the maximum distance an FM transmitter can broadcast without a license? The quick answer is approximately 200 feet for an FM Transmitter covered under Part 15 (Read FCC Public Notice dated July 24, 1991). The full answer is much more complicated than that: 250 µV/meter @ 3 meters (also measured as 48 dBuV/m).

Why FM is used?
FM is commonly used at VHF radio frequencies for high-fidelity broadcasts of music and speech. Analog TV sound is also broadcast using FM. Narrowband FM is used for voice communications in commercial and amateur radio settings. In broadcast services, where audio fidelity is important, wideband FM is generally used.
Why do we use FM?
FM broadcasting is capable of higher fidelitythat is, more accurate reproduction of the original program soundthan other broadcasting technologies, such as AM broadcasting.Therefore, FM is used for most broadcasts of music or general audio (in the audio spectrum).
What is the range of FM radio?
about 88 to 108 MHz
The frequency band for FM radio is about 88 to 108 MHz. The information signal is music and voice which falls in the audio spectrum. The full audio spectrum ranges form 20 to 20,000 Hz, but FM radio limits the upper modulating frequency to 15 kHz (cf.
Why FM is less noise than AM?
Amplitude modulation is also used to refer to medium wave AM broadcasting.During the modulation process, the noise is amplitude modulated. Since it only changes the amplitude of the carrier, it does not damage the message signal. Therefore, FM signals are less susceptible to noise than AM signals.
What is difference between FM and PM?
Phase Modulation is a modulation in which the phase of the carrier wave changes according to the instantaneous amplitude of the modulating signal keeping amplitude and frequency constant.
Difference between Frequency Modulation and Phase Modulation :
| S.NO. | Frequency Modulation | Phase Modulation |
|---|---|---|
| 10. | In FM, received signal is of high quality. | In PM, received signal is of low quality. |
