Synchronous read channel integrated circuit employing discrete time timing recovery

摘要

A synchronous read channel is disclosed which samples an analog read signal from a magnetic read head positioned over a magnetic disk medium, filters the sample values according to a partial response of the form (1-D)(1+D)n where n>1, extracts timing information from the filtered sample values, and detects an estimated data sequence from the filtered sample values using a discrete time sequence detector.
