Systems and methods for a data processing using integrated filter circuit

Abstract

Systems and methods are disclosed relating generally to data processing, and more particularly to applying low pass and rotation filtering in relation to data processing. For example, a system may include a phase modification value determination circuit operable to generate a phase offset value based upon an input data set derived from information sensed from a storage medium. The system may include an integrated low pass and rotation filtering circuit operable to simultaneously apply a low pass filtering function and phase rotation function to a series of digital samples derived from the information sensed from the storage medium to yield a modified output. Application of both the low pass filtering and phase rotation functions is governed at least in part based upon a selected coefficient set corresponding to a combination of the phase off set value and a boost value.
