METHOD FOR ELIMINATING INTERFERENCE IN A BIPOLAR DATA STREAM AND CIRCUITRY FOR IMPLEMENTING SAID METHOD

摘要

The invention concerns a method for eliminating interference in a bipolar signal on important line lengths. The signal is routed into a corrector for coarse tuning and fine tuning, and up o a level detector (12) mounted downstream and is fed back from the level detector to the corrector (9) by means of a control device (14). The scanning is carried out by means of a measurement clock signal. The scanning clock signal is measured such that the underscanning can be carried out. Three reference levels are used from each of which is derived a scanning digital signal. A coarse tuning or a fine tuning is initiated based on a number of violations above or below the threshold which can be predetermined according to a percentage.
