Engineering Contradiction Analysis
1Productivity
If separate timing acquisition and data parameter modification processes are used, then data processing can be performed, but processing overhead increases
Solution Approach 1:
The patent combines the low pass filter and rotation filter into a single integrated filter circuit that processes digital samples simultaneously. The circuit uses shared components including a single coefficient storage element, common control logic, and unified data flow paths, thereby reducing processing overhead while maintaining data processing functionality.
Solution Approach 2:
The integrated filter circuit performs multiple functions simultaneously: it applies low pass filtering to reduce noise, applies rotation filtering to compensate for rotational variance, and uses shared coefficient storage and control mechanisms. This multi-functionality eliminates the need for separate processing stages, reducing overall processing overhead.
2Loss of time
If integrated filtering is used, then overhead is reduced, but circuit complexity increases
Solution Approach 1:
The patent merges the low pass filter and rotation filter into one integrated circuit structure. Both filtering operations share common elements including coefficient storage, control logic, and data processing paths, which reduces the overall circuit complexity compared to implementing separate independent filter circuits.
Solution Approach 2:
The integrated filter circuit is designed to perform multiple filtering functions simultaneously using unified hardware resources. The circuit accepts digital samples and applies both low pass and rotation filtering through shared computational elements, reducing the total number of components required while maintaining comprehensive filtering capability.

AI summary
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.
