Abstract

In the field of knock detection in a combustion engine, a method and a device detects and controls the knock by adapting the gain of an amplifier which amplifies the knock sensor signal. The gain of the amplifier is adapted based on analysis of a set of samples from the knock sensor so that the amplification of the knock sensor signal across the entire measuring window is optimum and the complete ADC evaluation range can be utilized better.
