Abstract: An autoequalizer having first and second data stores, first and second coefficient stores along with first and second multipliers for multiplying each stored data sample times its corresponding stored coefficient is disclosed. First and second accumulators accumulate the results of the first and second multipliers for an entire window of consecutive data samples. The results from the first and second accumulators are summed with feedback before being tested against various threshold values. In a preferred arrangement, for use with dual information channels, mirror image equalizer elements are connected in a feedback arrangement with each other.
