Abstract
A method and apparatus for timing acquisition of partial response class IV Signaling is described. The invention uses an acquisition logic block to determine an output sequence that best matches a preamble pattern. The logic block analyzes current quantizer output X and the two previous decisions X.sub.n and X.sub.n-1. The logic uses these values to determine the next value X.sub.n+1 so that the best match occurs. The invention is implemented with OR gates, AND gates, and D flip-flops and can operate in acquiring mode or tracking mode.
