Abstract

PURPOSE:To reject temporary misconversion due to noise, by using the logical gate output of decision by majority every rank bit of a plurality of data as the A/D conversion output. CONSTITUTION:The output of each rank bit converted with the A/D conversion 1 is fed to the series input terminal of the shift register 2 consisting of the registers 21, 22 in cascade connection to store a plurality of data in A/D conversion at the past sampling time. The output of the logic gate 3 by decision by majority every rank bit taking the output of the A/D conversion section 1 and the registers 21, 22 as inputs in used as the A/D conversion output data. Temporary misconversion data due to noise can be rejected by referencing the conversion data of a plurality in the past by means of the decision by majority logic gate every rank bit.
