Claim 0:
1. A system for transmitting a value via a pulse-width-modulated signal, said system comprising:
a transmitter configured to detect the value and output a first pulse-width-modulated signal having a first pulse width which represents the value or a range around the value, on a signal line; and
a receiver configured to derive the value or the range from a voltage on the signal line representing the outputted first pulse-width-modulated signal, by evaluating the first pulse width;
wherein the transmitter is configured to read back the outputted first pulse-width-modulated signal from the signal line and check whether the value or the range is capable of being derived from the outputted first pulse-width-modulated signal and, if the value or the range cannot be derived, output an error signal to the receiver; and
wherein the transmitter is further configured to output a second pulse-width-modulated signal having a second pulse width which is in a range accepted as valid by the transmitter and the receiver, and wherein the error signal is a third pulse-width-modulated signal having a third pulse width which is outside the range accepted as valid.
