Abstract
The invention is directed to a method for adapting decision levels in the conversion of a multi-level analog signal into a digital signal, and to a digital receiver. As starting condition a certain level difference between two levels and also a first logic state, which the analog signal represents at the beginning of the data transmission, are predetermined. A second logic state is recognized in that the level of the analog signal varies by more than the level difference. A decision level is then calculated continually which lies between the levels of the first and second logic state.

A method for adapting a decision level in the conversion of a multi-level analog signal into a digital signal, wherein as starting condition a certain level difference between two levels and also a first logic state, which the analog signal represents at the beginning of the data transmission, are predetermined, wherein a second logic state is recognized in that the level of the analog signal varies by more than the level difference, and wherein a decision level is then calculated which lies between the levels of the first and second logic state.
A digital receiver for implementing the method according to any one of the preceding claims, characterized in that it includes an A/D converter for sampling and digitizing an analog signal as well as several registers for the storing of digitized sampled values.
