This is a difficult question to answer. Digital signals in television and audio are hailed as the "best" quality but there are many factors that affect the quality of both analog and digital signals.
Digital signals are not prone to quality loss once they are in a digital form. The data that makes up the signal can normally be stored, transmitted and received without error so the quality will be identical from start to finish. Analog signals can suffer from interference and losses which increase with the length of transmission line and with every active process used as the signal is stored and delivered. Therefore, in terms of quality loss, digital is likely to be the better medium.
Digital signals in video and audio are frequently compressed. Raw HD data needs a data rate of 1500 megabits per second but broadcasters frequently compress an HD signal to as little as 6 megabits per second. The compression process inevitably results in a loss of detail and a loss of quality. SD data rates are 270 megabits as an uncompressed signal but are compressed to as little as 1-2 megabits for broadcast. Again, the signal quality suffers. Analog signals are always broadcast as full bandwidth signals so they do not suffer from quality loss due to compression.
The final judgment regarding the best signal must be based on the quality of image seen. Without doubt, digital signal processing can deliver quality that most analog signals can never achieve but in reality, that is not always the case. Highly compressed digital television signals can often show a variety of unpleasant effects such as jerky movement and large blocks of the image without detail. As broadcasters devote more bandwidth to digital signals, the quality will improve but the quality is dependent on sufficient bandwidth for each signal.
There will be many differing opinions on this topic but it must always be accepted that "digital" does not automatically mean "better".
What else can I help you with?
What is the best signal processing either a analog signal processing?
Digital signal processing is the best compared to analog signal. It is because the digital signal is moreefficienterror freeimmune to noisethan an analog signal
Is digital electronics is the best or analog electronics?
They have their own merits and demerits you can't say digital electronics is best because in real world everything is available in analog quantity. Although Digital electronics is more reliable in comparison of analog because there is very high reliability in the sense (effect of noise) and correction of errors that occurred during transmission of digital signal, while this is not possible in analog communication.
Lexmark X5320 fax machine support digital dial tone?
Not to the best of my knowledge you would still require an analog phone signal.
How can you receive regular analog stations with a converter box?
this will depend on your area of living. check your local tv station for your best signal. also analog is going away so you cant really get a analog station.. that's why the converter box is for to receive digital transmitions
How do you convert analog speedometr to digital speedometr?
You cannot. The best thing to do is fit an additional digital speedometer.
Where can an analog to digital converter be purchased?
An analog to digital converter can be purchased at any large electronic store such as Best Buy or Radioshack. It can also be purchased at large retailers like Walmart and Target.
What is the best order for connecting digital and analog devices to a power strip?
I doubt that it matters.
Exampl for analog communication?
In Analog communication, the analog message signal modulates some high carrier frequency inside the transmitter to produce modulated signal.this modulated signal is then transmitted with the help of a transmitting antenna to travel through the transmission channel. At the receiver, this modulated signal is received and processed to recover the original message signal. Example: AM , FM radio transmission an TV transmission.
What is analog device?
Analog devices are machines and components that react or work in a linear manner, often with an ability to make a continuous change. For example, a volume knob on a radio could be an analog device because it controls audio power output over a continuous range. Many amplifiers, power supplies, and radios use analog devices for generating or processing analog signals. Digital devices are machines and components that are always found in one specific state or another, rather than in some range between two points. Many analog and digital systems are designed to simulate the best features found in the other type of system, e.g., analog controls on a digital CD player, or digital controls on an analog radio.
Difference between analog and hybrid computer?
analog computers,continuous quantities are used. computation are carried out physical quantities such as voltage,length,current,temperature etc. the devices that measure such quantities are analog devices example voltmeter,ammeter.hybrid computer the best qualities of both the digital and analog computer. hybrid computers are best used in hospital. hybrid computers are also used in wheather forecasting.
Which is the best text book for digital signal processing?
Signal processing and linear systems by B.P LATHI
Which one is best analog or digital computer?
Both, depending on application, budget, technology available, etc.
