EAS – Extended addition and subtraction

Block SymbolLicensing group: STANDARD

Function Description
The EAS block sums input analog signals u1, u2, u3 and u4 with corresponding weights a, b, c and d. The output y is then given by

y = a * u1 + b * u2 + c * u3 + d * u4 + y0 .

This block propagates the signal quality. More information can be found in the 1.4 section.

Input

u1	First analog input of the block	Double (F64)
u2	Second analog input of the block	Double (F64)
u3	Third analog input of the block	Double (F64)
u4	Fourth analog input of the block	Double (F64)

Parameter

a	Weighting coefficient of the u1 input $⊙$ 1.0	Double (F64)
b	Weighting coefficient of the u2 input $⊙$ 1.0	Double (F64)
c	Weighting coefficient of the u3 input $⊙$ 1.0	Double (F64)
d	Weighting coefficient of the u4 input $⊙$ 1.0	Double (F64)
y0	Additive constant (bias)	Double (F64)

Output

y	Analog output of the block	Double (F64)
