Abstract:
1. An apparatus including an adaptive signal equalizer, comprising: adaptive equalization circuitry tat receives at least a plurality of adaptive coefficient signals and in response thereto receives and equalizes an input data signal to provide an equalized signal; signal slicer circuitry, coupled to said adaptive equalization circuitry, that receives and slices said equalized signal to provide a sliced signal and a difference signal corresponding to a difference between said equalized signal and said sliced signal; and adaptive coefficient signal generator circuitry, coupled to said signal slicer circuitry and said adaptive equalization circuitry, that receives said plurality of adaptive coefficient signals, receives said input data signal and said difference signal and processes said plurality of adaptive coefficient signals and one of said input data signal and said difference signal to provide first and second aligned signals which are substantially temporally aligned, and processes said first and second aligned signals together to provide said plurality of adaptive coefficient signals.
