Read Channel With Oversampled Analog To Digital Conversion

摘要

Methods and apparatus are provided for processing a signal in a read channel using an oversampled analog to digital conversion. An oversampled analog to digital conversion is performed on an analog input signal to generate a plurality of digital samples corresponding to the analog input signal for a given bit interval. A data detection algorithm can then be applied on one or more of the digital samples to obtain a detected output. The oversampled analog to digital conversion simplifies the analog design by transferring at least a portion of the equalization and/or filtering processes to the digital domain.
