Abstract
A method and an apparatus for slicing a multilevel analog signal using a two-level slicer having one threshold level to generate an analog error signal. The method may be performed by delaying a received multilevel analog signal in a plurality of serial analog stages (n), further delaying a multilevel analog signal tapped from stage n, combining the further delayed signal from stage n with an analog error signal e(t) to provide an analog weighting function W, wherein the combining of the delayed signal from stage n with Wresults in a plurality of signals XW, summing the plurality of signals XW, slicing a multilevel analog signal resulting from the summing of the plurality of signals XWusing one threshold level to generate the analog error signal e(t), and combining the delayed signal from stage n with W.
