Yes, If you perform a windowed Fourier Transform of a truly periodic signal using a window function exactly one cycle wide the results will be exactly the same signal frequency spectrum, regardless of where on the signal you placed the window function. But you should also realize the results will also be the same signal frequency spectrum using a window function of any width that is an integer multiple of one cycle (greater than zero), or even without any window function at all. This signal frequency spectrum contains all the information needed to determine what is commonly called the bandwidth of the signal (and that spectrum often contains frequencies outside that bandwidth, but usually only at very low amplitudes so that their loss in filters, etc. is not generally considered significant).

Is the signal with zero frequency a periodic signal?
No, because for a signal to become periodic it must repeat itself in regular intervals of its time period.A 0 Hz signal has a time period equal to infinity , so technically the signal can never complete a full cycle by reaching infinity let alone repeat itself, since the signal is unable to repeat itself in regular intervals its not periodic.
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.
How many OC3 in an OC12?
An OC12 is equal to 4 OC3 bandwidth connections.
Does the number of protons equal the periodic number?
Yes, the number of protons in an atom is equal to its atomic number, which is also known as the periodic number.
What is the sampling theorem?
Answer The most common sampling theorem is known from Harry Nyquist, 1889 -1976. It is the foundation of digital audio. In 1928, Nyquist wrote a paper called "Certain Factors in Telegraph Transmission Theory" where he proved that for complete signal reconstruction, the required frequency bandwidth is proportional to the signaling speed, and that the minimum bandwidth is equal to half the number of code elements per second.
How do you connect onewireless broadband to ten computers and use same bandwidth same speed?
You can't ! Each computer would require an equal share of the available bandwidth from the router !
When signal amplitude is equal to carrier amplitude then modulation index is?
amplitude modulating signal
Why optical fibers has large bandwidth?
Study the optical transmission property of glass, to learn more. also: http://en.wikipedia.org/wiki/Optical_fiber You might wish to refine the question to differentiate between optical bandwidth and data bandwidth. If a laser can be modulated and the beam directed through an optical fiber, then the data or the analog bandwidth is about equal to the modulation bandwidth capability of the laser in Hz per second.

What element in the periodic table has a molar mass equal to one?
hydrogen
In periodic table of elements it is equal to the number of protons in the nucleus.?
The atomic number is equal to the number of protons in the nucleus.
What virtual world doesn't take up band width?
Bandwidth is used whenever you are on the internet, so unless it is offline there are no virtual worlds that use no bandwidth. However, most Internet Service Providers have very high bandwidth caps, usually about 250 GB (which is equal to downloading 250 movies) or no cap at all, so you don't need to worry about bandwidth so much.
