The Variable Delay component delays the input $u$ by a duration $\mathrm{\tau }$ given by a second input.

The delay input, $\mathrm{\tau }$, must meet the condition $0\le \mathrm{\tau }\le {\mathrm{\tau }}_{\max }$.

The Signal Size parameter assigns the dimension of the input and output connectors.

$y\&equals;\{\begin{array}{cc}u\left(0\right)& t<\mathrm{\tau }\\ u\left(t-\mathrm{\tau }\right)& \mathrm{otherwise}\end{array}$
