Abstract
An information handling system communicates information across a physical link with high and low signal values sent at a unit interval. Feed forward equalization improves signal transfer with pre-emphasis of low-to-high signals and de-emphasis of high-to-low signals lasting for a fraction of the unit interval, such as one-half or one-quarter of the unit interval. Fractional unit interval pre-emphasis and de-emphasis reduce inter symbol interference to improve frequency domain eye structure at the physical link receiver.
