The input terminal (1) is coupled to the output terminal (2) via an equalizing unit (3) and a limiter circuit (7).  The output (5) of the equalizing unit (3) is coupled to a first point of constant potential (16) via a clipper circuit (20).  The output (8) of the limiter circuit (7) is coupled to the input (6) via an impedance (23).  Further, the input (6) is coupled to a second point of constant potential (earth) via an integrating element (24).
