Number of Taps vs Tap Spacing in simulation 2 taps enough to open the eye for the 3 different tap spacings 25-ps tap spacing did not appear to benefit from more than 2-taps additional taps, for 12.5-ps & 6.25-ps tap spacing, increased the recovered eye amplitude 7-tap, 6.25-ps tap spacing most versatile --can be configured as a 2-tap FFE w/ 25-ps tap spacing --can be configured as a 4-tap FFE w/ 12.5-ps tap spacing
