Abstract: A circuit board, for use with a high speed backplane, includes transmitter and receiver with circuitry for correcting for multipath signal errors. A training sequence that is often a pseudo-random signal is transmitted by the transmitter on a first circuit board to a receiver located on a second circuit board. The receiver on the second circuit board includes an analog-to-digital signal converter, an equalizer, and a binary digital-to-analog reconverter for receiving the training sequence. The equalizer preferably comprises a series of connected registers having taps in between, a plurality of individual weighting means attached to each of the taps, and a summing means connected to the weighting means. A training sequence is transmitted from the first circuit board to the receiver on the second circuit board, enabling the receiver to adaptively determine a set of weighting means coefficients for correcting the multipath errors in subsequent signals.
