Abstract
An analog-to-digital conversion apparatus includes an interleaving unit operable to align the digital data respectively output from the plurality of analog-to-digital conversion units; and a correction arithmetic unit operable to correct a data value error of a data sequence caused by an error of a frequency characteristic for each of the plurality of analog-to-digital conversion units. The correction arithmetic unit includes a data partitioning unit that partitions the data sequence into a plurality of partition data having a predetermined partition data number and respectively generates the partition data; an arithmetic unit that sequentially acquires the partition data and sequentially outputs data after correction made by sequentially performing correction arithmetic; and a data connecting unit that removes either of the duplicated data according to each partition data or the duplicated data and sequentially connects the data after correction.
