摘要:
A digital signal processing method has steps of pre-emphasizing a digital signal, and then processing the pre-emphasized digital signal through a non-linear device. In the pre-emphasizing step, an undershoot is applied to a first level of the digital signal at a positive signal transition or an overshoot is applied to the digital signal at a negative first signal transition.
