Abstract

PURPOSE:To uniform the bit distribution of code and then realize a certain value of signal voltage as well as a reduction of cross talk, by giving a bit shift to the code train with the sample unit or the like and then transmitting the code after exchanging them between the adjacent bits. CONSTITUTION:The PCM coder 2 is driven by the block source 11 to change the data from the signal source 10 into a code train. This code train receives an alteration of arrangement with every 2nd sample by the processor 15 to be synthesized 14 with the delayed 13 code train. This synthetic code train receives and exchange of bit arrangement by the processor 16 and then changed into a complement with every 2nd bit by the processor 17 to be delivered. Then each bit position is restored at the reception side.
