Algebraic methods for reconstruction of coordinates in strip detectors

Many types of detectors, such as cathode strip chambers and some MPGDs, allow us to reconstruct track positions by induced strip charges. There are two main types of algebraic methods for this reconstruction: center of gravity methods and little-known differential methods. General formulas for differential methods are derived. Their performance is compared with the performance of center of gravity methods. It is shown that the differential methods are better than the previously known center of gravity methods, but the improved center of gravity methods provide results similar to the results of differential methods.
