Abstract

PURPOSE:To prevent a digitization error due to a noise from remaining for a long period by setting a comparator and an addend and subtrahend large in the initialization for the start of system operation and then by gradually decreasing them. CONSTITUTION:Comparator 11, when a level difference between (a) and (b) exceeds its set level, generates an effective comparator output and is variable in set level. Adder-subtracter 12, only when the output of comparator 11 is effective, performs addition and subtraction and its addend and subtrahend can be varied. In the initialization for the start of system operation, the set level of comparator 11 and set values of the addend and subtrahend are set large and then decreased gradually. Thus, the addend and subtrahend are increased between initialization points of system operation so as to quicken the rise of digitization, preventing a digitization error due to a noise from remaining for a long period.
