Abstract
The present invention relates to a method for processing a digital signal through a linear device. The digital signal makes a transition from a first level to a second level. The method comprises pre-emphasizing the digital signal before/after processing it by the linear device. Pre-emphasizing the digital signal includes: pre-emphasizing the digital signal by applying an undershoot to the first level before the 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 transition, when the first level is higher than the second level. The present invention also relates to an apparatus using the above method.
