H03M1/1052 - CPC Classification

Classification description:

Analogue/digital conversion; Digital/analogue conversion; Calibration or testing; Calibration over the full range of the converter, e.g. for correcting differential non-linearity by storing corrected or correction values in one or more digital look-up tables using two or more look-up tables each corresponding to a different type of error, e.g. for offset, gain error and non-linearity error respectively
