View source for Analog-to-digital conversion

A continuous signal is best represented as a continuous line having an [[amplitude]] value at all points in time, while a discrete signal is actually a sequence of separate [[amplitude]] values and thus is most accurately represented by separate discrete bars rather than a line. For a computer to record speech, it is necessary to convert the continuous sound wave (analog) into a discrete signal (digital) that can be stored on the computer. Two steps are involved in this '''analog-to-digital conversion'''. First, the continuous signal is chopped up in time into a sequence of 'samples'. Secondly, measuring the [[amplitude]] of the waveform at each time point corresponds to 'quantisation' (cf. [[quantisation noise]]). These two steps convert the continuous signal into a set of digits.
