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.

What does Armstrong modulator generate?
Armstrong modulator generates FM signals.
What is a tuned amplifier?
an amplifier with a narrow band pass used to tune into a carrier 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 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 narrow band modulation frequency?
When the frequency sensitivity of the modulating signal is small,the bandwidth of the FM is narrow. The narrowband FM has one carrier term two sideband terms.The modulation index is also small compared to one radian.
With regard to FM signal modulation how will a decrease in modulation voltage affect the FM signal spectrum?
Answer: A decrease in the audio voltage will resort in a to narrow band and will be difficult for the receiver to detect the audio.
A modulated waveform that contains a carrier plus two sidebands for each modulation frequency is a description of?
Both AM and narrow-band-FM.
Is FM Static and Thousand Foot Krunch the same band?
No, TFK and FM Static are not the same band
What is narrow band and wide band FM and How it can be generated?
In frequency modulation system, the maximum usable deviation be fixed +- 5 KHz and test deviation be kept 60% i.e. 3 KHz for wireless telephony systems used in military and other organisations. But wide band fm systems used in commercial broadcasts having frequency deviation +- 75 KHz.
FM static band is a Christian band or not?
yes, they are.
What is FM frequency?
A: This term refers to the FM band or frequency range.
What is the broadcast band of Metro FM Lagos nigeria?
97.6 Fm
What are the Operating frequency for AM and FM?
The AM radio band falls in the comparatively low frequency range of 550 to 1600 KHz while FM radio operates in the 88 to 108 MHZ range and CB operates in the relatively narrow range of 26.95 to 27.405 MHZ. Cellular telephone operates in a frequency band of 825 to 890 MHZ.
How many FM stations can be placed on an FM band?
100 stations are allowed
Does a 1997 Honda civic have a narrow or wide band oxygen sensor?
it has a narrow band.
