Question
Analogue vs digital
Answer
Analogue is continuous and may take any value in its range; digital is discrete and takes one of a finite set of values.
Question
What is sampling?
Answer
Measuring a continuous signal at intervals and recording each measurement as a number, so it can be stored digitally.
Question
The two sampling choices
Answer
Sample rate (how often you measure) and bit depth (how finely each measurement is recorded).
Question
Is digital better than analogue?
Answer
It is more robust — copies do not degrade. It is not automatically more faithful: a digital recording is always an approximation.
