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 are the advantages of digital data compared to analog data?
Digital data requires less bandwidth than analog data (e.g. new digital television broadcast compared to old analog broadcast), so more data can fit in the same frequency (e.g. DSL compared to analog modems). This is the primary advantage, although it is also generally stated that data is easier to recover and more tolerant towards interference.

What came first digital or analog service?
Analog services came first, as they were the primary means of communication and broadcasting before the advent of digital technology. Analog systems, such as traditional radio and television, transmitted signals in continuous waves. Digital services emerged later, utilizing discrete signals to improve the quality and efficiency of data transmission, leading to advancements in communication technologies.
What are digital converters used for?
Digital converters are used to convert an analog input into a digital current. They also have converters that covert from digital to analog. These are used for older model TVs that need to take a newer digital technology input but the tv still requires analog.
What is the term for a device that converts digital data from a computer into analog signals and back again?
The devices are known very simply as analog to digital converters and digital to analog converters. They are frequently shorted to A-D and D-A converters. A complete analog to digital converter will not only convert the analog signal into a set of numbers, it will also format the digital data ready to deliver to the next step in the signal chain. In television, this means generating a fairly complex stream of data that will carry not only the picture but audio and other data as well. Digital to analog converters reverse the process and use the incoming data to generate an analog signal. In television, well know examples are the digital set top boxes. They receive digital data from an antenna and convert the numbers into analog audio and video signals.
Where can one buy analog to digital tv converters?
Analog to digital television converters are a popular item that are widely available in department stores, electronic stores, discount stores, office supply shops, home improvement stores, warehouse clubs and even some dollar stores such as Dollar General. Online, they can be ordered from both Amazon and eBay.

If your Vizio LCD TV only has an optical audio output how do you hook up your RCA cables that go to your stereo?
You need to buy a "Digital to Analog audio converter" (around $70 with Gefen brand). It will convert the Digital output (Optical) into a analog signal for your speakers. These converters rarely provide RCA cables(male/male) and Optical Cable(male/male). So you will have to buy them too. http://www.gefen.com/kvm/dproduct.jsp?prod_id=5279
Why dac is required?
Digital-to-Analog Converters (DACs) are required to convert digital signals, which are represented as discrete values, into analog signals that can be used by various devices, such as speakers, televisions, and sensors. This conversion is essential for enabling digital devices to interact with the analog world, allowing us to hear sound, see images, or control physical systems. Without DACs, digital systems would be unable to effectively communicate or produce results in a format that can be perceived by humans or utilized by other analog devices.
Is GE TV Model 27GT617 analog or digital?

What is the history of digital television?
The time it took to change analog television signals to all digital took about 25 years. It started around 1986 and many television stations had converted over to digital signal by the year 2010.
