What is the connection between the bandwidth of a signal and the data rate that it represents?
The data rate (C) is equal to the bandwidth (B) times the logarithm base 2 of 1 plus the signal-to-noise ratio (S/N) (how much interference is introduced in the transmission of data)C = B x log2(1 + S/N)So your data rate is directly proportional to your bandwidth. If you increase your bandwidth, your data rate will also increase provided the signal-to-noise ratio isn't affected.
What does a telecom shelter contain inside?
A telecom shelter contains transmitters inside.
Why AM is used for long distance communication?
AM has a frequency range of 531 kHz to 1602 kHz and on the other hand FM has a frequency range between 8705 MHz to 108 MHz. If we talk about the bandwidth of AM then it is 1071 KHz and bandwidth of FM is 20.5 MHz.According to the bandwidth FM should be used for long distance transmission but it is not used for long distance but AM is used fir long distance transmissions. the answer is here.Long distance transmissions are also decided by the Spectrum of the Signal in frequency domain by doing the Fouriertransform of the Signal.If we draw the Spectrum of AM waves the we find that their is a main loop in the central part of the spectrum with a high frequency and on the left and right side of this loop their are side loop which are very smaller then the main loop. In FM information can be recover from the main loop only not from the side loops. On the other hand in AM waves all the loops in spectrum is of same size and information can be recover from all the loops.That is why AM is used for long distance transmission.Thnx -Vipin Jasoria
Does a low bandwidth signal have more power than a high bandwidth signal?
A low bandwidth signal does not have more power.
What is the general purpose of a bandwidth meter?
It measures the bandwidth, or amount of data, which a user has used. This is useful for companies which have limits to the amount of bandwidth they have sold, or who sell bandwidth at a price per gigabyte.
What is relationship between signal spectrum and bandwidth?
Signal Bandwidth is the Bandwidth of particular frequency at which signal is transmitted and Bandwidth of spectrum which can able two show number of signal between Intrest of frequency.
What is visible light frequency bandwidth?
Bandwidth of the visible light portion of the Electromagnetic Spectrum is approximately 384 Tera Hertz.
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 the name used to describe a section of the electromagnetic spectrum?
Perhaps you are after the word band or bandwidth.
What is a band plan?
A band plan is a plan for distributing or allocating bandwidth within a frequency spectrum.
What about 2g spectrum?
2G is means nothing but the wireless mobiles which was introduced in second generation are call as 2-G . spectrum is means nothing but it is a bandwidth which was given by government of India
What is spectrum in telecom?
Wireless communications make use of the radio portion of the electromagnetic spectrum. Simply put, telecom operators send and receive signals at various frequencies to enable communication. This radio spectrum contains only a limited number of frequencies. Signals can be sent on different frequencies all at the same time, however, if frequencies are the same or too close they can interfere with each other. As the number of frequencies is limited, they need to be allocated to different service providers. Therefore, spectrum is allocated for various communication purposes world-wide. Is spectrum being given free to telecom operators? Contrary to popular perception, spectrum is not available for free. Currently, spectrum charge has two components - the entry fee charged is inclusive of one-time spectrum charge, and an annual spectrum charge based on a percentage of the Adjusted Gross Revenue (AGR) of the telecom company. The percentage of annual spectrum charges for GSM operators, for instance, varies with spectrum usage. Currently, the ceiling for annual spectrum charge is 6% of AGR. Trai, though, has recommended that the ceiling be lowered to 4%. Now, Trai's recommendations only say that there will be no one-time spectrum charge for allocation of IMT-2000 spectrum (meant for 3G) for existing service providers. The regulator has explained that the allocation to the existing operators should be viewed as extension of 2G spectrum allocations. However, a contrary view is that spectrum is a scarce resource and that additional allocation should be priced. Regards, Kanak New Delhi
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)
