Abstract:
A system for the transmission of binary data between a number of stations which are interconnected via a common first line and a common second line, the first line having a low potential and the second line a high potential for one logic value of the binary data whereas the first line has a high potential and the second line a low potential for the other logic value of the binary data, the logic value of the binary data being derived from the potential of at least one line, for output on a data output, said system comprising:a first station including a first comparator coupled to both lines and configured to subtract the potential on the first line from the potential on the second line and provide an output signal of a first value via a first comparator output if the difference formed by the subtraction exceeds a first threshold value, said first threshold value being chosen so that the output signal of the first comparator also changes its value if a potential transition occurs on only one of the two lines and the other line has a potential corresponding to the one logic value of the binary data.
