Abstract

Digital information transmission system components including at least one unit arranged to transmit signal elements in parallel, at least one unit arranged to receive signal elements in parallel, and a corresponding plurality of signal transmission paths connected between such units to each convey a respective one of the signal elements, in which a unit serving to transmit such signal elements is constructed for selectively creating, in each path, a signal element in the form of a signal state representing either one of two binary values or a signal state different from that representing either such binary value; and a unit serving to receive such signals is constructed for producing a response which distinguishes between the appearance, in each path, of either binary value state or the different state.
