Definition: linear time-invariant transfer element the output variable of which reproduces the input variable shifted by an interval equal to the dead time

Note 1 to entry: The transfer function of a dead-time element is given by

$\frac{V\left(s\right)}{U\left(s\right)}={\text{e}}^{-s\cdot {T}_{\text{t}}}$

where
 Tt is the dead time; s is the complex variable of the Laplace transform; U(s) is the input transform; V(s) is the output transform.

Note 2 to entry: Transportation lags of mass, energy or information are described by dead-time elements.

Note 3 to entry: This entry was numbered 351-28-42 in IEC 60050-351:2006.
