A knocking detecting apparatus for an internal combustion engine with a knocking detector for detecting a factor of knocking in the engine and a circuit for generating a knocking discrimination level in response to the output signal of the knocking detector, for detecting knocking by comparing the output signal of the knocking detector and the knocking discrimination level. The knocking detecting apparatus comprises a circuit for clamping the output of the knocking discrimination level generator circuit such that the knocking discrimination level does not exceed a predetermined voltage.
