<p>The arrangement (1) has a frequency switch via which an input signal generated in a generator (2) is delivered to a high tone group (4) with arrangement of high pass filters (10, 11) and to a low tone group (6) with an arrangement of low pass filters (8, 9). The high tone group has a delay element (12) such that output signals of the high tone group and low tone group with different signs are added to a total signal, where filter corner frequencies and filter qualities of the high tone group and the low tone group are adapted to delay time of the delay element.</p> |
