  • Page 120: Glossary

    Bar Height The dimension of a bar measured perpendicular to the bar width. Bar Width Thickness of a bar measured from the edge closest to the symbol start character to the trailing edge of the same bar. Baud Rate A measure of the data flow or number of signaling events occurring per second.
  • Page 121 Continuous Code A bar code or symbol in which all spaces within the symbol are parts of characters. There are no intercharacter gaps in a continuous code. The absence of gaps allows for greater information density.
  • Page 122 Depth of Field The range between minimum and maximum distances at which a scanner can read a symbol with a certain minimum element width. Discrete Code A bar code or symbol in which the spaces between characters (intercharacter gaps) are not part of the code.
  • Page 123 The exact (or ideal) intended value for a specified parameter. Tolerances are specified as positive and negative deviations from this value. Standard size for a bar code symbol. Most UPC/EAN codes can be Nominal Size used over a range of magnifications (e.g., from 0.80 to 2.00 of nominal).
  • Page 124 A minimum PCS value is needed for a bar code symbol to be scannable. PCS = (RL - RD) / RL, where RL is the reflectance factor of the background and RD the reflectance factor of the dark bars.
  • Page 125 A scannable unit that encodes data within the conventions of a certain symbology, usually including start/stop characters, quiet zones, data characters, and check characters. Symbol Aspect Ratio The ratio of symbol height to symbol width. Symbol Height The distance between the outside edges of the quiet zones of the first row and the last row.
