A tap/group-revivable decision feedback equalizing method and equalizer using the same is disclosed. The equalizer includes a feed-forward filter and a feedback filter each with a plurality of taps divided in groups. The tap/group-revivable decision equalizing method includes training all the taps to generate their tap coefficients, and selecting all the taps of any of the groups with a tap coefficient greater than a predetermined value and selecting a number of taps of any of the groups without a tap coefficient greater than the predetermined value, but with a neighboring group with a tap coefficient greater than the predetermined value are selected, and having the selected taps utilized for equalization. |
