The polynomial function code implements a seventh order polynomial.
Output = Ax7 + Bx6 + Cx5 + Dx4 + Ex3 + Fx2 + Gx + H
Two specifications define the coefficients A through H:
Tunable mantissa value.
Nontunable power of ten.
The actual value of the coefficient is the product of the mantissa and the power of ten. For example:
A = S16 x 10S17 = Aman x 10Aexp
NOTES:
When function code 167 is utilized as a shaping algorithm for analog in/channel (function code 222), its tunable specifications are not adaptable.
When function code 167 is used as a shaping algorithm, it can not at the same time also be used as a logic function because the block output will not respond to the specification S1 input.
Multiple instances and combinations of function code 177 and 222 function blocks may utilize the same function code 167 function block as a shaping algorithm. The function code 167 shaping algorithm function block is not required to be in the same segment as the function code 177 or function code 222 blocks.
