DivisionTest

Division operation that divides a first input by a second input.

Performs a simple division operation where the output y = u1/u2, dividing the first input (u1) by the second input (u2). This component requires that the second input (denominator) is non-zero to avoid division by zero errors.

Usage

DivisionTest()

Behavior

$$\begin{array}{rl}\mathtt{division}\mathtt{.}\mathtt{u}\mathtt{1}\left(t\right)& =\mathtt{c}\mathtt{1.}\mathtt{y}\left(t\right)\\ \mathtt{division}\mathtt{.}\mathtt{u}\mathtt{2}\left(t\right)& =\mathtt{c}\mathtt{2.}\mathtt{y}\left(t\right)\\ \mathtt{c}\mathtt{1.}\mathtt{y}\left(t\right)& =\mathtt{c}\mathtt{1.}\mathtt{k}\\ \mathtt{c}\mathtt{2.}\mathtt{y}\left(t\right)& =\mathtt{c}\mathtt{2.}\mathtt{k}\\ \mathtt{division}\mathtt{.}\mathtt{y}\left(t\right)& =\frac{\mathtt{division}\mathtt{.}\mathtt{u}\mathtt{1}\left(t\right)}{\mathtt{division}\mathtt{.}\mathtt{u}\mathtt{2}\left(t\right)}\end{array}$$
