Classification: H04L

Abstract:
Method for equalizing digital signals received after transmission, wherein a received signal (1) is evaluated based on thresholds (U.sub.1 . . . ), characterized bycarrying out a threshold decision with at least four threshold decision elements (2), wherein at least one multiplexer (4) connects outputs of the threshold decision elements (2) to a subsequent delay unit (6), wherein the at least one multiplexer (4) is responsive to at least one regenerative output signal (9, 10) of the delay unit (6) byadaptively adjusting the thresholds (U.sub.1 . . . ) of the threshold decision elements (2) by means of a digital processor unit (12) and by carrying out regeneration of the at least one output signal of the delay circuit (6) in response to a data clock pulse (C) and by adjusting thresholds of the threshold decision elements (2) in a time frame slower than a time period of said data clock pulse.
