A method for recovering data includes oversampling an input data signal to provide sample sets, and storing a plurality of sample sets in addressable memory. The sample sets are processed, using sequential logic to make determinations of respective samples suitable for use in data recovery from corresponding sample sets. One function applied for the determination, includes taking a first mean transition position in a first group of sample sets, taking a second mean transition position in a second group of sample sets, computing a slope value for change in transition position, and making the determination based on the order of the plurality of samples, the first and second means, and the slope. The determined samples are obtained and data recovery is achieved. Sample sets can be modified according to equalization functions. Other modifications include encoding the sample sets for data compression.
