Adaptive angle sensor

A method comprising: obtaining at least three sampled values m, each of the sampled values m including a respective first component that is obtained based on a first signal and a respective second component that is obtained based on a second signal and solving a system of equations to yield at least one of (i) an offset adjustment vector k, (ii) a sensitivity mismatch coefficient γ, and (iii) a non-orthogonality coefficient s, the system of equations being arranged to model each of the sampled values m as a function of: a respective one of a plurality of number arrays, a magnetic field, and the at least one of (i) the offset adjustment vector k, (ii) the sensitivity mismatch coefficient γ, and (iii) the non-orthogonality coefficient s.
