Abstract
A system for compensating for variations in an output consisting of many components that show variations, comprising a memory for storing the compensation value for each component, an analog-to-digital converter for converting the output into several bits of digital output, a multiplier for multiplying the value of the high order bits of the digital output by the compensation value, and a subtracter for subtracting the output of the multiplier from the value of the low order bits. Instead of using the multiplier, the order of the value of the high order bits can be lowered down to that of the value of the low order bits, and the obtained value can be subtracted from the low order bits the number of times indicated by the compensation value.
