There are two types of modulations. They are amplitude modulation and frequency modulation. In AM, amplitude of the signal is modified. In FM, frequency is getting modulated. Frequency modulated with carrier waves are transmitted and received by receivers without any distortion.

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 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.
What is the bandwidth of FM?
88 MHz-108MHz
Do FM transmitter MP3 player connections lose sound quality?
Since the signal is passed over radiowaves, you can expect to lose some sound quality depending on which FM transmitter you purchase.
What makes FM radios different from AM radios?
AM radio is KHz FM radio is MHz AM radio can cover the world. FM radio can cover a county. AM radio is excellent in communication. FM radio is completely worthless, except for good sound quality. AM radio doesn't have as good sound quality as FM. FM is much higher on the radio spectrum than AM.
Why do radio stations use FM for high quality music?
FM is not used to broadcast high quality music. FM is how the broadcast is carried out on to the airwaves. The high quality sound comes from the stations transmitter, compression, and different equipment to give the audio a good, crystal clear sound. Hope this helps!
What are FM waves?
FM radio uses frequency modulation to broadcast sound over radio. FM radio waves are usually transmitted between 87.5 to 108.0 megahertz.
Are tv sound and picture sent through FM waves?
Picture is AM, sound is AM or FM
When was Liffey Sound FM created?
Liffey Sound FM was created in 2006-09.
When was Amber Sound FM created?
Amber Sound FM was created on 2008-10-04.
When was West Sound FM created?
West Sound FM was created on 1990-05-21.
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 difference between narrowband FM and wideband FM?
wide-band is used for high quality transmission Narrow-band is used for speech & data k.vijayvardhanbabu
What is radio AM?
AM - Amplitude Modulation FM - Frequency Modulation AM radio is simply lower frequency sound waves caused from the transmitter. This can cause the sound to become very soft or loud at stages. Static sound can also me heard from house hold appliances interfering with the Radio. The quality of the Radio can be heard less better than FM.
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.
