A computer only reads information in digital coding (binary) a truly analog signal would not register in a computer.

What is the term used when digital values are converted to create an analog sound?
When digital values are converted to create an analog sound, the term used is Digital-to-Analog converter.
Does sound have to be converted from digital to analog for a computer?
No. Sound has to be converted from analog to digital for use by a computer, not the other way around. It is converted to analog so amplifiers and other analog equipment can use it and so you can hear it.
What are AD and DA?
AD is Analog to Digital conversion the use is to do digital measurements of analog voltages and currents, a computer soundcard is an AD converter that convert analog sound to digital sound so that it can be played on a computer, and DA is the opposite, digital to analog conversion, the digital sound on the computer is converted to analog sound to drive a speaker or headphone
Where can one find information about an electric digital to analog converter?
Information about a digital to analog converter can be found on the site Hardware Secrets which divulges that real world signals such as light and sound can be converted into digital signals by a circuit called ADC (Analog-to-digital converter) so that the information, once converted, can be processed and stored digitally.
How may analog media be converted to a digital format?
digital imaging (using digital cameras and scanners), sound cards, and analog video-capturing devices sample, compress, and convert analog media into a series of 0s and 1s (digital) signals for processing by a computer
Can you input straight from your HD TV to a sound bar?
Yes. Use the digital outputs, if the sound bar has the same type of input, otherwise use the RCA analog inputs.
How do you output sound from a Phillips lcd tv 42pfl5432d 37 to a Bose Cinemate series ii system?
If your TV has a digital out, connect this optical output to the optical digital input on the Bose. If your TV doesn't have a digital out, you can connect the analog audio out (red and white) to an analog input on the Bose.
How do you connect the HDMI digital cable to the surround sound?
If your receiver has an HDMI input, use that. If it doesn't, then you will have to use analog or digital audio connectors to plug it in.
Is Sound digital or analog?
Sound itself is always analog, though the quality varies. Things on a a computer, iPod, TV, etc. are represented and transmitted digitally, but it is converted back to analog before it gets to the speakers. An example of analog sound storage would be a record player. While both are voltage, digital media is written in 1's or 0's, then converted back into a semi analog voltage to drive a speaker. To the trained ear, modern music which is stored digitally still doesn't sound as good as analog, due to loss in some of the frequencies we hear. Another way to create or transmit sound is acoustic, which is that of a nonelectric guitar or saxophone.
Difference between analog simulator and digital simulator?
The big difference is inputs and outputs. Digital ICs expect high/low true/false inputs and outputs. Analog ICs take any inputs, and produce outputs of any level. For example, an audio amplifier is an analog IC. It takes an analog input (sound), and produces an analog output (louder sound). A ripple counter is an example of a digital IC. It takes a digital input (clock pulses), and produces a number of digital outputs (the digital outputs of the flip flops, collectively representing a number in binary).
Why must sound and video input to a PC be converted from analog to digital?
Because in order to preserve the original sound, a digital sampling rate must be twice the frequency of the analog signalAnalog data is smooth and continuous, where as digital data, such as the binary data used in computers, has distinct gradations. The process of producing digital data by measuring data at a series of representative points is called sampling.
How do you amplify video signal?
Voice being analog signal will be converted by an ADC whereby the output is a logic representation of the analog input
