Abstract
An error processing circuit for a receiving location of a system for transferring binary data in the form of pulse sequences, wherein the system has a number of receiving locations connected via a double-line bus having a first line and a second line. The circuit includes a data output, a decoder having three decoder outputs, of which a first decoder output associated with both lines delivers a first decoder output signal dependent on the difference between the potential values of both lines, a second decoder output associated with the first line delivers a second decoder output signal dependent on the difference between the potential value of the first line and a first mean potential value, and a third decoder output associated with the second line delivers a third decoder output signal dependent on the difference between the potential value of the second line and a second mean potential value. A line condition detector circuit detects error-free line conditions, line errors of the first line, and line errors of the second line, depending on the decoder output signals, and changeover control signals can be delivered to a changeover switch to deliver properly decoded data, depending on the particular detection result.
