Why do most networks transmit digital rather than analog signals?
Digital signals are capable of carrying more information than analogue signals because digital signals make use of the bandwidth more efficiently by closely approximating the original analogue..
Does a low bandwidth signal have more power than a high bandwidth signal?
A low bandwidth signal does not have more power.
The telephone line the bandwidth for the voice is usually the bandwidth for data?
Because voice communication uses more information to reproduce the person's tones and qualities over the line. Data is a digital signal composed of 1 & 0 - needing much less bandwidth.
What is a sentence for bandwidth?
The lawyer did not have the bandwidth to handle another case. The bandwidth was more than adequate to transmit the data quickly.
What does the abbreviation HDCP mean?
HDCP is the abbreviation for High-bandwidth Digital Content Protection. It protects material from being distributed illegally between more than one person.
Why digital signals are better than analog signals?
according to my view, to deal with digital signal is more easy then that of analog. and it also stable so many of the semiconductor circuits run only on dc signals...... i think doubt is clear now....
Why did the US change to digital?
Digital TV, you mean? It was to provide more bandwidth. Supposedly, programs were going to be sharper, clearer BUT of course networks and station owners went the shoddy route: more channels, each one no better (and usually worse) than the analog channels they replaced.
What is relation between roll off factor bandwidth and bit rate?
The roll-off factor of a digital filter defines how much more bandwidth the filter occupies than that of an ideal "brick-wall" filter, whose bandwidth is the theoretical minimum Nyquist bandwidth. The Nyquist bandwidth is simply the symbol rate expressed in Hz: Nyquist Bandwidth (Hz) = Symbol Rate (Sym/s) However, a real-world filter will require more bandwidth, and the excess over the Nyquist bandwidth is expressed by the roll-off factor. Suppose a filter has a Nyquist bandwidth of 100 MHz but actually occupies 120 MHz; in this case its roll-off factor is 0.2, i.e. the excess bandwidth is 0.2 times the Nyquist bandwidth and the total filter pass-bandwidth is 1.2 times the Nyquist bandwidth.
Why did the Inca sacrifice animals more than humans?
It is easier more economical
Are rechargeable flashlights more economical than regular flashlights?
In theory, yes, rechargeable flashlights are more economical than regular flashlights, however you have to be careful to not overcharge your batteries otherwise they will run out quickly
Is low bandwidth signal has more power than high bandwidth signal?
no,because generally the lower frequency side existed for lower bandwidth,and higher frequency side existed higher bandwidth,so thus we can say that lower bandwidth has generally has lower power as compared to higher bandwidth.
What kind of gas will last more miles?
DIESEL is more economical than normal petrol/gas
