Abstract: An apparatus for correcting imperfectly equalized bipolar signals includes a delay line having a reset control, an AND gate, and a one-shot multivibrator. The apparatus is used in conjunction with an adaptive equalizer with the output of the adaptive equalizer being coupled to the input of the apparatus of the invention. More particularly, the output of the equalizer is coupled to the input and reset of the delay as well as to one input of the AND gate. The output of the delay line is coupled to the other input of the AND gate. The output of the AND gate is coupled to the input of the one-shot multivibrator and the output of the one-shot multivibrator is the corrected signal. The delay line is approximately equal to the pulse width of an erroneous pulse which is expected from over-equalization. When the delayed signal is compared to the original signal via the AND gate, narrow pulses are removed from the signal.
