System and method for providing a full fail-safe capability in signal transmission networks

A receiver circuit, comprising:

• a first offset signal generating unit;
• a second offset signal generating unit;
• a first signal comparing unit;
• and
• a switching unit to couple an offset signal from at least one of the first offset signal generating unit and the second offset signal generating unit to an input of the first signal comparing unit.

A method of providing a fail-safe capability in a signal transmission network, comprising:

• receiving a plurality of signals in the signal transmission network;
• if a polarity of the plurality of signals is a first polarity, adding a first offset signal to the plurality of signals;
• and
• if the polarity of the plurality of signals is a second polarity, adding a second offset signal to the plurality of signals.
