Abstract
A sub-field array is formed by providing a sub-field corresponding to an m-th bit sub-field (m and n being a positive integers of m.ltoreq.n and representing the most significant bit place when m is 1) bit substantially at the center of the time axis of all the sub-field periods, and providing the other sub-fields than the m-th significant one on the opposite sides of and substantially in line symmetry with respect to the m-th significant bit sub-field. Less significant bit sub-fields are provided on the opposite sides of the close proximity of the central sub-field in the field period, and the odd and even order sub-fields are arranged in opposite sequences from one another. As the symmetrical arrangement sub-fields, odd and even scan line sub-fields are provided on the opposite sides of the central sub-field.
