An element is provided which operates in two selectable mode. The element converts the analog output of a knock sensor to a digital value in one mode and compares the analog output with the reference value in the other mode. The average output of the knock sensor is calculated from the digital value and the reference is calculated from the average output. In the occurrence of any knocking, the output of the knock sensor is greater than the reference.
