Today, we use digital technology to transfer information. A digital electric signal is a bit stream (i.e., a sequence of two-state voltage or current pulses, denoting by 1 or 0). So, the basic element of information is the binary digit or bit.
As a consequence, we define the digital bandwidth as the amount of information per time unit that can propagate reliable over a communication channel (that is, a transmission medium, such as a copper wire cable). Digital bandwidth is measured in bits per second (bps) and its multiples (kilo-, mega-, giga-, etc.).

What is visible light frequency bandwidth?
Bandwidth of the visible light portion of the Electromagnetic Spectrum is approximately 384 Tera Hertz.
How can the Doppler effect cause broadening of a spectral line?
Perhaps this broadening of the spectral line might be due to different propogation speeds under Doppler conditions when the emitting object is moving towards us? Therefore increasing the frequency shift and spreading the spectrum over a wider bandwidth. Or perhaps Take an amplitude modulated carrier wave with a fixed modulating frequency. Un-shifted the sidebands would remain constant in width. If the signal source was moving towards us the modulating frequency would also increase. The increased modulating frequency would move the sidebands further away from the carrier, increasing bandwidth or broadening the spectrum.
What is the name used to describe a section of the electromagnetic spectrum?
Perhaps you are after the word band or bandwidth.
Which band of the electromagnetic spectrum has the lowest frequency?
That would be sound waves, or the audio spectrum.
How frequency and wavelength related to specific region of the spectrum?
what
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 a band plan?
A band plan is a plan for distributing or allocating bandwidth within a frequency spectrum.
A periodic signal with a bandwidth of 70khz and highest frequency 200khz all frequencies have amplitude of 110v draw the spectrum in frequency domain utilizing Microsoft Excel charting facility?

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)
What is meant by a low pass signal?
A low pass signal whose bandwidth is much smaller than its center frequency, such as an AM signal. It is a a signal with its spectrum concentrated around zero frequency.
What is the relation of frequency and bandwidth?
Frequency is a measure of the number of occurrences of a repeating event per unit time. The bandwidth of a frequncy is simply the difference between the upper and lower frequencies.
What is the frequency spectrum?
Scroll down to related links and look at "Frequency spectrum - Wikipedia"
How does the frequency change in a FM transmitter?
-- the modulation index varies -- the instantaneous deviation varies -- the amplitude of the carrier component varies -- the spectrum of sidebands varies -- the total occupied bandwidth varies
If the frequency spectrum of a signal has a bandwidth of 500 Hz with the highest frequency at 600 Hz what should be the sampling rate?
The Nyquist Therorem states that the lowest sampling rate has to be equil to or greather than 2 times the highest frequency. Therefore the sampling rate should be 400Hz or more.
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
