What is correction?
Correction is the application of a specified mathematical function upon transducer data from one or more STIM channels and/or data delivered from other software objects. Correction is intended to reconcile 2 different numbers associated with a transducer channel. These two numbers are:
How is correction applied?
The goal of correction depends on the transducer type.
What is the correction function?
D (1) D (2) D (n)
... >C i, j,...,p[X1 – H1] i [X2 – H2] j ... [Xn – Hn] p
i = 0 j = 0 p = 0
where the Xk variable (inputs) represent the data from a set of channels (taken from the transducer or NCAP side) and D(k), C i, j, ... p and Hk are data recorded in the Calibration TEDS. D(k) is the degree of input Xk, that is, it is the highest power to which [Xk – Hk] is raised in any term of the multinomial. The degree of each input may differ from another.
