Concatenation Rules

Simple addition is not always the appropriate technique to "add" two values from attributes of the same type together. Concatenation rules provide algorithms to add various types of attributes. The five attribute concatenation rules available in netWorks are as follows:

Sum (+)
r = a₁ + a₂
PowerSum ( $\oplus$ )
$r = 10 * log_{10} ( 10^\frac{a_1}{10} + 10^\frac{a_2}{10} )$
NegPowerSum ( $\ominus$ )
$r = -10 * log_{10} ( 10^\frac{-a_1}{10} + 10^\frac{-a_2}{10} )$
LengthFactor
r = a₁ + (a₂ * Length)
NoiseLoss
$r = (noise_1 \oplus noise_2 ) - loss_2$
