### 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

$\mathtt{\text{y}}=\mathtt{\text{a}}\ast \mathtt{\text{u1}}+\mathtt{\text{b}}\ast \mathtt{\text{u2}}+\mathtt{\text{c}}\ast \mathtt{\text{u3}}+\mathtt{\text{d}}\ast \mathtt{\text{u4}}+\mathtt{\text{y0}}.$

Inputs

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