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.
