System and method for sensor response linearization

摘要

A system and method for generating a linearized sensor signal p from a sensor signal m using a kth-degree polynomial The coefficients of the kth-degree polynomial can be calculated using a least-squares method by a computer. The computer can calculate for 1<j<=k the (2j-1) root of the jth coefficient aj of the kth-degree polynomial and download the coefficients and the resulting roots rj to a storage device in a digital signal processor (DSP). For 2<j<=k, the DSP can calculateand multiply the result byThe resulting terms can be added to the calculation of a1m to generate the kth-degree polynomial. The kth-degree polynomial is the linearized sensor signal.
