	The second problem is that data is only recorded at discrete times. We do not know what the signal - for example, the sound wave - is doing between the measurements. More than one possible wave can fit. This problem is called [[aliasing]]; it can also be mitigated by taking more frequent measurements but never totally solved.

+A '''digital''' system is a mathematical system in which numbers shift between discrete states instead of rotating continuously. For example, an [[abacus]] was a digital [[calculator]] because in it a bead had to be all the way up or all the way down; there was no meaning for a bead partially up or down. Electronic calculators and modern [[computer]]s are also examples of digital systems, because they depend on logic gates which need to be either on or off - there are only two possible states.
 The name comes from the [[Latin]] term [[digit]], which means "[[finger]]".
