What is Baseband Signalling?
A signal which has frequencies from 0 to some band-limited value B.ORwe can sy that baseband signal is a signal that can include frequencies that are very near zero, by comparison with its highest frequency(e.g: a sound waveform can be considered as a baseband signal, whereas a radio signal or any other modulated signal is not baseband.)
What is baseband filter?
A baseband filter is a device that only passes frequencies inside the interval (0,B), where B is the maximum frequency of the signal.Example: The human voice occupies a spectrum from 0 Hz to 3400 Hz, aproximately. A baseband filter would only let those frequencies pass.The difference between a band-pass and a baseband filter is that the latter is a band-pass filter with its lower cut frequency being 0.
Is demodulated carrier wave grounded in environment. if yes how. if no what happens to it?
During demodulation of AM the carrier beats with the sidebands reproducing the baseband signal. In other systems it is more complex, but in all the carrier is removed by the demodulator and baseband filter that follows the demodulator.
What is baseband connection?
Electrical signals are found in different parts of the frequency spectrum. A baseband signal is an "original" signal that directly conveys the frequency range of the original: a hi-fi audio signal is commonly 20 Hz to 20 kHz, analog video (European) is 50 Hz to 5 MHz. A baseband signal *does not* use a modulated carrier, no matter how high or low its frequency. Any signal that *does* use modulation is *not* a baseband signal. Radio (and other) transmission systems use the baseband signal to modulate a carrier before sending. On reception, the modulation is extracted to become a copy of the original baseband signal.
You will have signal degradation unless you use the amplifier.?
You will have signal degradation unless you use the amplifier.
Why carrier signal is always in analog signal?
It isn't always. Baseband analog signals have no carrier.
Why Only one signal can be transmitted in baseband?
i need the answer very urgent
What is bandwidth required for AM signal?
With full double sideband AM the bandwidth of the modulated signal is twice that of the baseband information signal. With suppressed carrier single sideband AM the bandwidth of the modulated signal is identical to that of the baseband information signal. With vestigial sideband AM the bandwidth of the modulated signal is somewhere between the above two cases, depending on how much of the vestigial sideband is included.
How effective is a cable TV signal booster in terms of picture quality?
TV signal boosters will significantly improve the picture quality of your TV if the poor quality you are currently experiencing is due to signal degradation. If the cable signal is poor from the source, a signal booster will not help.
Differences between baseband and broadband?
Baseband is a type of transmission that uses current to send a signal over the wire as digital wave. Broadband uses analog signal to transmit thru different frequencies, which increases the amount of data carried at one time.
Explain if transmit baseband signal directly in a wireless system and why?
An antenna must be the order of magnitude of the, wavelength signal in size to be effective. Using only baseband transmission, FDM could not be applied and (Path loss, penetration of obstacles, reflection, scattering and diffraction. All the effects depend onthe wavelength of a signal.
What is the difference between analog and digital modulation Does it depends on baseband signal?
The basic difference is that in analog modulation the modulating signal is analog signal and in digital modulation it is in digital form.
