Narrow-Band (also referred to as short-wave) is a term used to describe the amplitude of a radio device. Narrow-band devices are limited to an average of 400m.

What is different about the method used to boost digital signal strength compared to the method used to boost analog signal strength?
A digital signal requires a repeater, which retransmits the signal in its original form, and an analog signal requires an amplifier, which increases the strength of both the signal and the noise it has accumulated.
Laptop you get a wireless signal from a library across the street but your signal is very low sometimes no signal what can you do to get a better signal?
You could attach an external directional antenna. Google for 'wireless antenna'.
What is radar duplexer?
duplexer is the device that can separated the trasmitted signal and received signal.
How do you protect against a signal jammer?
how do we protect our cable network from signal jammer
A signal starts at point x as it travels to point y it loses 8 db at point y the signal is boosted by 10bb as the signal travels to point z it loses 7 db what is the db strength of the signal at point?
A signal starts at point X. As it travels to point Y, it loses 10db. At point Y, the signal is boosted by 5db. As the signal travels to point Z, it loses 7db. What is the db strength of the signal at point Z?
If data signal is narrowband compared to the spreading signal, the resulting product of both the signals will have what bandwidth of spreading signal?
.
Difference between broadband and narrowband noise?
Before sending your signal to the receiver,it should passed through the narrowband filter(whose band is narrow).the noise appearing at the output of the filter is narrowband noise..
Transmitter concentrates the signal energy at a single frequency or in a very small range of frequencies?
narrowband
A transmitter concentrates the signal energy at a single frequency or in a very small range of frequencies?
narrowband
Is DSL narrowband technology?
Yes
Is 468 MHz broadband or narrowband for radio?
Radio services that operate on 468 MHz may use both wideband (25 KHz) bandwidth and narrowband (12.5 KHz) bandwith until December 31, 2012. After that date, only narrowband bandwidth will be authorized. For additional accurate updated information on the FCC's 2013 Part 90 Narrowband Mandate, please see link.
What is a difference between broadband ISDN and narrowband ISDN?
Here are some differences between broadband ISDN and narrowband ISDN: 1) Narrowband ISDN uses 64 kb/s channel, while broadband ISDN uses 100 mb/s channels. 2) Broadband uses call relay, while narrowband uses frame relay. 3) In narrowband, ISDN information carries narrow frequency, while in broadband, ISDN uses a wide band of frequency.
What is narrow band modulation frequency?
When the frequency sensitivity of the modulating signal is small,the bandwidth of the FM is narrow. The narrowband FM has one carrier term two sideband terms.The modulation index is also small compared to one radian.
The Quality factor of a narrowband filter is always?
You cannot fix a cap on the range of quality factors :)
Are Both digital narrowband and broadband transmission speeds measured in megabits and gigabits per second?
true
What has the author Raymond Roy Hitchcock written?

What is the difference between wideband and narrowband?
In the Narrow-band channel the signal see the channel as a flat channel , and the signal pass the channel without any type of cut . In the other hand the signal that passes through the wide-band channel see the channel as a frequency selective channel and cut values from the signal . I mean that if the bandwidth for the signal is lager than the bandwidth for the channel then, the channel is a wide-band channel, and if the bandwidth for the signal is smaller than the bandwidth for the channel then the channel will be a narrow-band channel .
