Abstract (en)

[origin: WO0161953A1] The invention concerns a method for adapting decision levels during the conversion of a multilevel analog signal into a digital signal and a digital receiver. A given level difference between two levels and a first logic state, which is assumed by the analog signal at the beginning of data transmission, are present as starting condition. A second logic state, in which the change in the level of the analog signal is greater than the level difference, is then recognized. A decision level lying between the levels of the first and second logic states is then continuously calculated.
