Abstract
Disturbances in a bipolar signal in the case of large line lengths are suppressed. The signal is led to a coarse setting and a fine setting in an equalizer and to a downstream level detector. From there it is fed back to the equalizer via a control device. Sampling is performed in this case with the aid of a measuring clock pulse. The sampling clock pulse is dimensioned such that undersampling is carried out. Three reference levels are used, from which one digital sampled signal is derived in each case. A coarse setting or fine setting is initiated as a function of a percentage-prescribed number of upper and lower threshold violations.
