A circuit for generating a discrimination level voltage which is used as a reference voltage to discrlminate between two logic levels adjacent to each other in input signals which generally can be in a state corresponding to one of a plurality of different logic levels. The frequency at which the levels of the input signals lie in the upper half of the vicinity of the discrimination level and the frequency at which the levels of the input signals lie in the lower half of the vicinity of the discrimination level are compared and the discrimination level is controlled so that the above two frequencies are the same.
