Abstract
A data transmitter pre-emphasizes the amplitude and frequency bandwidth of a data signal. A data tap generator delays the data signal to generate multiple data tap signals, each of which is delayed by an integer multiple of a data period. A delay module further delays one of the data tap signals by a delay time that is less than the data period to generate a delayed data signal. The delay time of the delayed data signal determines a frequency bandwidth pre-emphasis for the data signal. A filter module multiplies the amplitudes of the data tap signals and the delayed data signal by coefficients to generate signal components of a pre-emphasized data signal. The coefficients of the filter module determine the amplitude pre-emphasis for the data signal. The filter module sums the signal components to generate the pre-emphasized data signal, which includes both the frequency bandwidth pre-emphasis and the amplitude pre-emphasis.
