5. Determine the sign of the gain correction factor using the sign bits from Step 2. If the
offset-corrected ADC value and the gain correction word both have the same sign,
then the factor is positive and remains unchanged. If they have differing signs, then
the factor is negative and must be multiplied by –1.

7. Shift the result to the right, using the sign bit determined in Step 1, to allow for the
detection of computational overflow.
