I don,t understand why digital is better than analoque, as far as i know analog is direct source.?

Question

If digital is better why to convert from digital to analog before it can be play in analog source?

Answer 1

The simple answer: digital is better because it travels with only 0's and 1's, and is not suseptable to noise in the line along the way as analog is.

However, in order for you to hear any sound coming from a digital signal, it has to convert back to analog at the speaker.

Answer 2

Although everything starts out as analog and ends up as analog, it's the stuff in between that causes the problems. Analog signals are deteriorated by noise and bandwidth limitations, and all of that deterioration shows up in the result. Digital signal also deteriorate, but such signals include error-detecting and correcting codes that can restore the signal to it's original quality even if some of it is destroyed. So, once converted to digital form, the signal can be transmitted, received, and reconstructed as an exact replica of the original (digital) signal. There are limits to this, however, and if enough deterioration occurs, the reconstruction will fail, and the result is garbage.

Answer 3

DIgital is simply a new way of doing things .. things that are new and coming in teh future, and old things too. You also can not effectively store analogue information as efficiently as digital information.

The entire path any sort of analogue signal travels down weakens the signal and potentially distorts it.

With a digital signal, it does get weakened, but it has no effect on the signal until it reaches a point of extreme degredation with so much loss that there is simply no signal. Digital is, essentially, all or nothing. Analogue just gets worse and worse.

As far as transmission goes.. well.. it's not all it's cracked up to be, but it is better than it was 10 years ago or so when digital cell phones came out, the networks are usually pretty good now, but if you get interference on an analog phone it cuts in and out and sounds bad, with digital, it pretty much just cuts out once the signal is too weak.

However, to say analogue is a "direct" signal is not really accurate. In the audio world, yes... Every part of a song, wether it comes from the mic or a guitar, bass, etc, starts as an analogue signal, where it goes from tehre depends on the gear used.

Answer 4

digital is better, we are converting from analog to digital. This is a digital world. And its better, FCC/GOV needs analog signals to use for emergency stuff and other things.
