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.

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.
Can you get FM broadcasts on a VHF receiver?
If you're referring to commercial FM "music, news, and talk" broadcasts, the answer is 'No'.Those stations all transmit on carrier frequencies between 88 MHz and 108 MHz. Your VHF receivermost likely doesn't cover those frequencies.Even if it does overlap the commercial FM band, at the end of its dial, the VHF receiver won't deliveranything worth listening to.A). It's basically an AM receiver, not FM.B). It might deliver a recognizable voice from a narrowband FM signal, but it isn't designed toeven admit the comparatively wide-band commercial FM signals.
Why FM transmission is limited to line of sight?
the high frequency, it is in VHF band.
How to get a pcb of 5 band am receiver is it available?
A: Why make it i can buy FM am receivers for a $1 made in china
What is FM transmitter and what are the different FM transmitters?
FM transmitter : In this case the frequency of a carrier signal is modulated/altered in accordance with that of frequency of modulating signal. TYPES OF FM TRANSMITTER: 1> directly modulated FM transmitter. 2>indirectly modulated FM transmitter. an FM transmitter is a portable device that plugs into the headphone jack or proprietary output port of a portable audio or video device, such as a portable media player, CD player, or satellite radio system. The sound is then broadcast through the transmitter, and plays through an FM broadcast band frequency. Purposes for an FM transmitter include playing music from a device through a car stereo, or any radio.
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 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.
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
FM static band is a Christian band or not?
yes, they are.
What is the broadcast band of Metro FM Lagos nigeria?
97.6 Fm
What is FM frequency?
A: This term refers to the FM band or frequency range.
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
When did Edwin Howard Armstrong invent the FM radio?
According to a recent book (Early FM Radio, by Frost), modern FM wasn't invented all at once, but evolved with the help of dozens of other people besides Armstrong. But Armstrong was the first to significantly widen the frequency swing. A hand-drawn sketch indicates that he hit on that idea in the summer of 1932. During the following January he filed two patent applications for wide-band FM, one of which has a similar sketch. On December 26, 1933, he was awarded four patents for FM radio (The other two were applied for in 1927 and 1930, but weren't for wide-band). He discovered in early 1934 that his invention was almost free of static.Armstrong took a few more years to give FM high fidelity, but by 1938 or 1939 he had improved FM to the point that it was our FM radio, minus the stereo sound.
