The total range of analog values that correspond to the ideal straight line.
NOTE 1 The qualifying adjective "practical" may nearly always be deleted from this term, provided that the term "nominal full-scale range" is not also shortened by deleting "nominal". This permits use of the shorter letter symbols or abbreviations. (See note 2.)
NOTE 2 In place of the letter symbols "VFSR" and "IFSR", the abbreviation "FSR" is commonly used; in place of the letter symbols "VFSRpr" and "IFSRpr", the abbreviation "FSR(pr)" is commonly used.
NOTE 3 The (practical) full-scale range has only a nominal value because it is defined by the end points of the ideal straight line.
EXAMPLE Using a straight binary n-bit code format, it follows that
FSR = (2n - 1) x (nominal value of step width), for an analog-to-digital converter, and
FSR = (2n - 1) x (nominal value of step height), for a digital-to-analog converter.
