What are the advantages of Digital Systems over Analog Systems?

1.In analog systems, noise are induced and amplified resulting in distortion and inaccuracy whereas digital system do not have this problem.
2.Digital System are more durable than Analog.
3.Digital systems have better resolution and analog.
4. Digital Systems requires less storage space than Analog.

admin answers:

Analog recording versus digital recording compares the two ways in which sound is recorded and stored. Actual sound waves consist of continuous variations in air pressure. Representations of these signals can be recorded using either digital or analog techniques.

what are the pros and cons of a digital audio system as opposed to an analog one?

its the old digital versus analog battle again.

I know that for the most part the world has switched from analog audio systems to more hi-tech digital ones, but is there anyone who feels like we lost something when we did away with analog systems?

I’m interested to see what you guys think we gained from digital and what you think we lost.

admin answers:

Well its really more about the receiver and the speakers than a tosslink or analog cable but if you paid an arm in a leg your going to say digital is so much better. We lost nothing nor gained anything they just sold more cables and speakers.

George asks…

what is difference between analogue systems and digital systems?

admin answers:

I am not 100% sure, especially on the digital end and many devices work differently depending on what they do. I will use TV (radio works the same) as my example

an analogue TV signal sends a different frequency of radio wave (light technically) for each pixel, color, and sound. These variations are small so it doesn’t use a huge part of the spectrum but there are a lot of them. A 4 pixel TV (talk about bad resolution) would have one frequency strengthening and weakening per color per pixel, 3 colors per pixel (RGB) means 12 frequencies used just for those few pixels that doesn’t even include the sound.

Digital signals consist of 1s and 0s. They have 2 (maybe 3 to act as spaces) frequencies transmitted very fast that a processor decodes and translates into the signal. The number of frequencies used also does not increase as the amount of pixels go up. The down side is that there more of a delay for the processor to decode the signal but the payoff is much more frequencies that can be used (we can only hit so many efficiently)
