Patent attributes
A signal conditioning arrangement includes a sensor arrangement for sensing a measured quantity and for outputting an output signal having a first or a second logical signal state based on the measured quantity, and means for generating an evaluating impulse if the logical signal state of the output signal does not change for a maximum predetermined time duration, and which are further formed to allocate a first or a second pulse signal state, which differs from the signal state of the output signal which the output signal has during the predefined time duration, to the evaluating impulse. Furthermore, the signal conditioning arrangement includes means for combining the output signal and the evaluating impulse, with means for providing being formed to provide a conditioned output signal, the conditioned output signal having, when an evaluating impulse is present, the impulse signal state thereof and otherwise having the logical signal state of the output signal.
