Abstract
A comparison unit compares polarities of a plurality of redundant input signals. A comparison-result storing unit stores a comparison result of the comparison unit for each predetermined sampling cycle. A judgment unit judges whether the redundant input signals are normal using a plurality of comparison results for a predetermined number of samplings in a time-series order from a latest comparison result among a plurality of comparison results stored in the comparison-result storing unit.
