A digital modulation methods is provided in which at a head of an input block (pre-translation), each of a plurality of different types of initial data of t bits is multiplexed to generate a plurality of different types of multiplexed blocks, t bits at the head and immediately following t bits of each of the multiplexed blocks are subjected to exclusive OR operation, the immediately following t bits are replaced by the result of operation, the replaced t bits and the immediately following t bits are subjected to an exclusive OR operation, and the immediately following t bits are replaced by the result of operation, and thereafter in the similar manner, convolution operation is executed, whereby a plurality of different types of translated blocks are produced by the convolution operation, and DC components of thus provided translated blocks are calculated respectively, absolute values of the respective DC components are compared with each other, and a translated block having the minimum value is selected and output externally. <IMAGE> |
