PURPOSE:To apply nBmB code conversion without increasing a data signal speed after the superimposition of a significant bit by constituting the code conversion rule of an input data black to be superimposed with the significant bit so as to be changed depending on the value of the significant bit and the bit combination of input data. CONSTITUTION:A new nBmB code conversion table is generated by changing an m-bit train not included in the old nBmB code conversion table and the order of use in the code conversion table in applying code conversion when changing the input data train with the nBmB (n<m) code conversion system. The new nBmB code conversion table is applied in the block interval decided in advance and the information other than input data information is expressed depending on the presence of the use of the code conversion table to transmit the significant signal without the addition of a significant signal train of the input data train. Then it is not required to interrupt the significant bit to the input data column and it is not required to increase the data transmission speed. |
