The present invention relates to emphasizing and de-emphasizing of an analog data signal. Using a main analog driver a data signal indicative of bit values of binary data is converted into a first analog data signal. A second data signal is determined by delaying the data signal a predetermined time interval and inverting the delayed data signal. Using a de-emphasis driver, the second data signal are converted into a second analog data signal, wherein the second analog data signal is additive to the first analog data signal if the data signal and the second data signal are indicative of a same bit value, and wherein the second analog data signal is subtractive to the first analog data signal if the data signal and the second data signal are indicative of an opposite bit value. The first analog data signal is emphasized or de-emphasized by superposing the first analog data signal and the second analog data signal.
