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 Bandwidth of RF amplifier?
That depends on its purpose. Some examples:RF amplifier in IF stage of AM radio: 10KHz.RF amplifier in TV set: 6MHz.RF amplifier in IF stage of FM radio: 200KHz.An RF amplifier in a military RADAR set will probably have very narrow bandwidth to reduce jamming possibility, but wide enough to allow for doppler shift of targets.
Is low bandwidth signal has more power than high bandwidth signal?
no,because generally the lower frequency side existed for lower bandwidth,and higher frequency side existed higher bandwidth,so thus we can say that lower bandwidth has generally has lower power as compared to higher bandwidth.
What is relation between roll off factor bandwidth and bit rate?
The roll-off factor of a digital filter defines how much more bandwidth the filter occupies than that of an ideal "brick-wall" filter, whose bandwidth is the theoretical minimum Nyquist bandwidth. The Nyquist bandwidth is simply the symbol rate expressed in Hz: Nyquist Bandwidth (Hz) = Symbol Rate (Sym/s) However, a real-world filter will require more bandwidth, and the excess over the Nyquist bandwidth is expressed by the roll-off factor. Suppose a filter has a Nyquist bandwidth of 100 MHz but actually occupies 120 MHz; in this case its roll-off factor is 0.2, i.e. the excess bandwidth is 0.2 times the Nyquist bandwidth and the total filter pass-bandwidth is 1.2 times the Nyquist bandwidth.
What is the difference between transmission bandwidth and channel bandwidth?
The transmission bandwidth refers to the range of frequencies that are being transmitted from one point to another. The channel bandwidth on the other hand refers to the frequencies of a given channel.
What is the bandwidth of DSBSC?
BW=2 fm
How is the bandwidth allocated in case of FM?
In Frequency Modulation (FM), bandwidth is allocated based on the modulation index, which is determined by the frequency deviation of the carrier signal and the frequency of the modulating signal. According to Carson's Rule, the total FM bandwidth is approximately twice the sum of the maximum frequency deviation and the maximum frequency of the modulating signal. This means that FM signals can occupy a wider bandwidth compared to Amplitude Modulation (AM), allowing for better noise immunity and audio quality. Typically, for standard FM broadcasting, the bandwidth is around 200 kHz.
Why AM is used in TV video signals transmission and not FM?
AM has a smaller sideband bandwidth than FM, since the baseband bandwidth of NTSC video is already about 4.5MHz, using AM vestigial sideband the resulting bandwidth is only just under 6MHz (without partially suppressing one sideband, the resulting bandwidth would have been about 9MHz). Had FM been used instead the resulting bandwidth might have been around 100MHz instead.
If the transmission bandwidth is doubled in FM then the SNR is?
decreases by 1/4
How much bandwidth is required to listen to Essex FM online?
There is no information available as to how much bandwidth Essex FM online radio takes. It is not as much as required, but how much it takes up is what the worry is for. Most internet providers have a limit as to how much bandwidth you are allowed to use in a month.

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.
Which require higher bandwidth FM or AM and why?
Frequency Modulation (FM) requires higher bandwidth than Amplitude Modulation (AM) due to the nature of how each modulation method encodes information. FM varies the frequency of the carrier wave to transmit information, which results in a wider range of frequencies being occupied. In contrast, AM varies the amplitude of the carrier wave, which occupies a narrower bandwidth. As a result, FM typically requires about 10 times more bandwidth than AM to accommodate the greater frequency deviations used in the modulation process.
What is essential bandwidth of FM signal?
"Essential bandwidth" is the portion of the signal spectrum that encompasses most of the energy of the original signal in the frequency domain.
What is wide band FM?
Wideband FM (WBFM) is a type of frequency modulation that uses a larger bandwidth than standard FM, typically exceeding 15 kHz. This increased bandwidth allows for higher audio quality and greater fidelity, making it ideal for applications like high-fidelity music broadcasting. WBFM is commonly used in television audio transmission and high-quality FM radio stations. Its wider bandwidth also makes it more resistant to noise and interference compared to narrowband FM.
How big is an FM?
An FM, or frequency modulation signal, can vary in size depending on its bandwidth, which is influenced by factors such as the audio signal's frequency content and the modulation index. Typically, FM signals can occupy a bandwidth of about 200 kHz for standard FM radio broadcasting. However, in digital communications, the size can differ significantly based on the specific application and encoding techniques used. Overall, the "size" of an FM signal is not fixed and depends on various parameters.
State and prove the sampling theorem?
If the signal is bandwidth to the fm Hz means signal which has no frequency higher than fm can be recovered completely from set of sample taken at the rate
What is the effect of varying frequency of the carrier signal on the AM wave?
spread spectrum , modulation or depending on the bandwidth poss FM (deviation)
