Claim:
A method for temporally analyzing serial input data, the method comprising: establishing a first threshold (V 1 ) to distinguish present high probability one bit value estimates; establishing a second threshold (V 0 ) to distinguish present high probability zero bit value estimates; establishing a third threshold (Vopt) to distinguish indefinite present bit value estimates between the first and second thresholds; distinguish present (first) high probability one bit value estimates; distinguishing present high probability zero bit value estimates; and, using a temporal analysis of bit values to distinguish indefinite present bit value estimates as follows: distinguishing a present bit estimate below first threshold and above the third threshold as a zero if both the past (second) and the future (third) bits are one values, as a one if only one of the past and future bits is a one value, and as one if both the past and future bits are a zero value; and, distinguishing a present bit value estimate above the second threshold and below the third threshold as a one if both the past and future bits are a zero value, as a zero if only one of the past and future values is a zero value, and as a zero if both the past and future bits are a one value.
