PROBLEM TO BE SOLVED: To provide a method for improving the quality and the integrity of a digital signal transmitted through a non-linear device or a bandwidth-limited channel.SOLUTION: The present invention relates to a method for processing a digital signal, which makes a first transition from a first level to a second level, through a non-linear device. The method includes a step of pre-emphasizing the digital signal; and a step of processing the pre-emphasized digital signal by the non-linear device. The step of pre-emphasizing the digital signal includes pre-emphasizing the digital signal by applying an undershoot to the first level before the first transition, when the first level is lower than the second level; and/or pre-emphasizing the digital signal by applying an overshoot to the first level before the first transition, when the first level is higher than the second level. The present invention also relates to an apparatus using the above method. |
