ABSTRACT:
A process for correcting the input-output correspondence of an analog-to-digital converter includes calculating the equation of the actual input-output correspondence, for known input values, during programmed conversion suspension periods. A comparison with the ideal conversion line subsequently makes it possible to calculate the necessary offset and gain corrections. The process is applied to the digital conversion of a plurality of component video signals.
