Abstract
In a knock detecting apparatus for an internal combustion engine, a comparator receives at one input a knock detection signal from a knock sensor and at the other input a knock discrimination level signal produced by a knock discrimination level generator in accordance with the knock detection signal of the knock sensor. A mask circuit inhibits the passage of the comparison output signal of the comparator during a period in which a number of noises are generated from the internal combustion engine and at the same time interrupts the operation of the knock discrimination level generator.
