Abstract
An apparatus for converting an analog input signal to a binary output signal, particularly for use in a facsimile system. The apparatus includes a reference level generator having its input terminal supplied with the analog input signal, a signal dividing circuitry connected between the input and output terminals of the reference level generator, an integrator having one end connected with the dividing output terminal of the signal dividing circuitry and the other end connected with a common potential level point in the apparatus and a comparator having one input terminal connected with the signal dividing output terminal of the dividing circuitry and the other input terminal connected with the input terminal of the reference level generator. The reference level on the basis of which the analog input signal is converted to a binary signal is thus adjusted for satisfactory conversion of the signal.
