Abstract
A device for signal evaluation is described, in particular for knock recognition in an internal combustion engine, in which the signals forwarded by sensors are evaluated digitally and error recognition is carried out that performs two different test functions, whereby a first test function supplies a test pulse at a specifiable location, and the second test function clears the sensor signals, and the reaction of both the analog and digital parts of the circuit are monitored.
