resolution (1) (general term)

The degree to which nearly equal values of a quantity can be distinguished or produced.

NOTE 1 Resolution as a capability can be expressed in different forms (see "resolution, analog", "resolution, numerical", and "resolution, relative").

NOTE 2 Resolution is a design parameter and therefore has only a nominal value.

NOTE 3 The terms for these different forms may all be shortened to "resolution" if no ambiguity is likely to occur (for example, when the dimension of the term is also given).

(2) (of an analog-to-digital converter): The degree to which nearly equal values of the analog input quantity can be discriminated.

(3) (of a digital-to-analog converter): The degree to which nearly equal values of the analog output quantity can be produced.
