Method and apparatus for the receiver-side elimination of static or temporally slowly variable interference signals from input data signals in the case of the digital data transmission in a predetermined bitmap

摘要

A method for the receiver-side elimination of static or temporally slowly variable optical or electrical interference signals from input data signals in the case of the digital data transmission in a predetermined bitmap, wherein the input data signals with a high-pass filter to be filtered, which has a time constant which is smaller than the bit, and in the data signals thus filtered input signal rises and signal waste are detected and an output data signal to a first predetermined signal level is set when a signal rise is detected, and to a second predetermined signal level is set when a decrease in the signal is detected, characterized in that the output data signal to the predetermined second level is set when a predetermined limit number of bit times after detection of a signal rise has elapsed.
