Abstract
Position information PosN and PosQ are compared and position information Posand Posin which influences of an error of a position sensitivity gain appear oppositely are calculated. Subsequently, a weight gain G=M and a weight gain G=(1−M) are obtained from the position information Pos. A multiplication value obtained by multiplying the third position information Posby the weight gain Gand a multiplication value obtained by multiplying the fourth position information Posby the weight gain Gare added and synthesized, thereby calculating a decoded position.
