ABSTRACT:
Disclosed herein is a data processing method wherein an analog processing object signal is compared with a reference signal and used to convert the processing object signal into digital data and a counting process is carried out and then a count value at a point of time at which the counting process is completed is retailed to acquire digital data of N bits of the processing object signal, including the steps of: carrying out counting operations using the first and second count clocks, whose frequencies are different by an amount corresponding to a weight of the bits from each other, independently of each other; and compensating for an excess or deficiency of data of the higher order N-M bits counted using the second count clock with respect to the count value counted using the first count clock within the counting operation enabled period.
