Abstract
Data transmission in, for instance, a PCM system, is effected by translation of the binary codes into ternary combinations such that to each binary code there is provided n ternary codes with the choice of the ternary code sent being dependent on secondary intelligence, such as signalling information and/or synchronization information, to be sent. In the example described a binary bit stream is split into three bit blocks each of which is converted into a three bit ternary code.
