FM is frequency modulation. The amplitude is held constant and the carrier frequency is varied.
AM is amplitude modulation. The amplitude is varied and the carrier frequency is held constant.

∙ 12y agoFM is not always better in the city it is because its not effected by buildings bridges etc am goes farther but gets bounced around ( i might have those mixed up but im pretty sure that's right)

∙ 9y agoFM radio is definitely considered better than AM radio by many people. Still others prefer AM radio over FM radio.

What is narrow band FM and how a narrow band FM generate?
If the modulation index of FM is kept under 1, then the FM produced is regarded as narrow band FM. Lower the modulation index, lower the no. of significant sidebands are produced (with reference to bessel function). So lower the no. of significant sideband, lowerer will be the bandwidth of the resulting FM prduced. Sometimes, Narrow Band FM is regarded as, when the significant energy in FM occupies the same bandwidth as ordinary AM with the same modulating signal.
How the modulation index varies for FM?
how modulation index varies for FM
How do you convert FM to PM and PM to FM waves?
In order to convert fm to pm, the modulation index must be set to be independent instead of having a variation. Then the receivers must be properly synchronized.
Why FM is preferred for audio signal transmission?
FM also known as frequency modulation is preferred because of the more concise ability to transfer quality sound at the expence of distance. Also FM is not as severely effected by weather as its lower frequency AM counterpart.
What is the bandwidth of FM?
88 MHz-108MHz
Why FM radio is better than am radio?
Actually, AM is better than FM. AM can cover the world, and is the best form of communication. FM is completely worthless except for the fact that it's better sounding.
Why FM is more clearer than am?
The abbreviations FM and AM stands for amplitude modulation and frequency modulation. The reason why FM is more clearer than AM is because FM has a better signal-to-noise ratio than AM does.
What is better FM or AM?
FM
What does fm and am stand for?
AM-Amplitude modulated FM-Frequency modulated Explanation: The frequency and amplitude refer to the width and height of wavelengths in the radio waves that are used to transmit the signal. FM is usually a better signal than AM because the frequency of the waves is less distorted than amplitude.
Which radio station is better FM 100 or SL100?
FM 100 is better because a bunch of people don't really listen to SL100 anymore.
Why FM is good than am in communication?
The FM signal is more amune to static in the atmosphere than AM signals.
Why do people prefer FM to Am?
FM radio has better sound quality and less background noise compared to AM radio. FM signals also have a wider bandwidth, allowing for more stations and better reception in areas with interference. Overall, FM radio offers a clearer, more reliable listening experience for most people.
Why am rather than FM in most used in mobile radio system?
FM and AM are both used in radio systems today. AM stands for amplitude modulation, and in AM radios, the signal goes farther but has more interference from objects and the weather. FM has a higher quality sound, and is used for its better music/sounds.
What is the diffirences for the listener between AM an FM?
AM and FM both are used in radios. They work in same principles, except FM is frequency modulation and AM is amplitude modulation. FM is much better than AM because it can travel a longer distance before dispersing.
Why FM is used for voice signal?
Analog radio uses either amplitude modulation (AM) or frequency modulation (FM) to carry an audio signal. AM signals can be received at greater distances than FM but they suffer from interference from other stations and a wide range of electro-magnetic sources. FM signals offer better quality with less interference than is typically found with an AM signal. The transmission range is far smaller than AM. For a wide geographic coverage, multiple transmitters are needed although the limited range also makes FM an ideal medium for local stations where long range is undesirable.
Which is better zune or iPod?
The zune is better because is supports more audio formats and is better priced than comparable ipod units. Ipods are the fashionable choice. Also, the zune can share wirelessly between players and has a FM radio tuner.
Is the hino fs bigger than the hino FM?
The further down the alphabet means the bigger the truck. So the Hino FS is bigger than the Hino FM.
