What is the difference between a digital phone and analog cordless phone?

Digital phones are more secure, can send both voice and data transmission, and has better sound quality. Analog phones are less expensive and only transmit voice.


What is the basic principle of digital television?

Digital television is simply the process of broadcasting a digital signal, instead of an analog one. This results in better sound and picture quality, as well as increased coverage.


What is the main advantage of digital transmission over analog transmission?

digital signal is less susceptible to signal degradation due to the nature of it's transmission signal which is either on or off and therefore less errors occur as analog is prone to signal degradation and loss that is why digital tv is crisp and clear and analog is somewhat blurry in comparison, also with higher bandwidth achievable by digital transmission more data is able to be transmitted.


Is analog recording better than digital recording?

The digital recording gear is much cheaper and lighter than the analog gear. So everybody can feel like a real sound engineer if one has a sound card - but one can still study "Tonmeister". The sound does not depend on the difference between digal and analog. It comes from excellent playing artists in a room with good acoustics, studio microphones, and a sound engineer with sensitive ears.


What is better-digital or analog communication?

It depends on applications. At the middle - short distances analog communication can be much more efficient than digital. If you work in communications, you may find the explanation - why? in IEEE Comm. Letters, vol.16, no. 5, 2012, pp.573-576, as well as in my Research Gates Profile. With regards.

How are digital aerials different from analog ones?

Digital aerials get a better quality of picture than do analog aerials. in addition, digital aerials can get high definition signals over the air,where analog aerials cannot.


Why are digital computers popular?

Well it is kind of simple really but digital has better graphics and says to run faster.The reason is simple: ease of programmingDigital computers can be programmed by writing code, which can be reloaded at any time.Analog computers usually have to be "taken apart and rewired" to be programmed.In fact, when built with the same technology, Analog computers are always faster than Digital computers at solving the same problem. However Analog computers have not been built since the 1980s (and then only for special purposes) so Analog computing technology now lags Digital computing technology by several decades.


Will a set top box improve signal quality for your TV?

Set top box is basically used to convert the digital signals broadcasted by digital signal broadcasters to analog signals, in case you wish to have your analog tv, but would like to have an access to digital channels. Digital channels definitely have better quality signals than analog and therefore you will have a better picture quality and signal quality even though you have converted the digital signals to analog.


digital video camera vs analog.?

Yes, the picture quality of a digital video camera is a lot better than an analog camera. They are fantastic for filming sports events.

If you have a digital tv and an outdoor antennae do you need a converter box?

In the US the answer is probably not. Digital and analog TV broadcasts use the same frequencies and antennas. Digital TV is more fussy about signal quality than the older analog signals. So if you get marginal analog reception, figure on getting a new antenna for digital. The idea that there are special HDTV antennas is just marketing hype. Any antenna that gives you better digtial reception will also give you better digital reception.


Is there an spdif analog audio out?

No, a S/PDIF is, by definition, a Sony / Phillips Digital Interconnect Format connector, and is always a digital signal. It is usually connected by an RCA cable, and can be carried by cable specified for analog use, but digital cable is better.


How has digital music changed the music industry for the better?

Digital recordings do not have the hiss, crackling, or other artifacts of older systems like the vinyl record or cassette tape. Digital recordings do not degrade as quickly as analog recordings. There is still some debate about whether digital recordings sound better than analog vinyl records, however.


Digital or optical audio cables which is best?

They are about equal in quality. Far better than the analog hookup.

What is the difference between a cellular phone and a telephone?

In an analog phone, the mechanical energy of sound (speech) is picked up by a microphone (mic) and converted into an (analog) electrical signal. This signal is then put through whatever electronics stages are required (if any) to get the signal onto a phone pair for transmission to the receiver. In a digital cell phone, the mic picks up the sound and converts that into an analog electrical signal. That analog signal is then sent to an electrical stage called an analog-to-digital (A to D) converter. Once the signal is digitized, it can be treated as a data string and amplified and broadcast (to the cell hub) as such. An incoming call is a digital data string that is D to A converted in the phone and then the newly recovered analog signal is made to be heard by the user. The difference between the two is the conversion and re-conversion (analog to digital and digital to analog) in the digital cell phone.


Why digital signal is better than analog signal?

the digital code is binar. so if you get a signal it is absolut. analogue signals can be interfered or altered through interferation.
