Integral of the time-weighted absolute error $(ITAE)$ is expressed as
1. $\int _{0}^{\infty }\frac{\left | \varepsilon \left ( t \right ) \right |}{t^{2}}dt$
2. $\int _{0}^{\infty }\frac{\left | \varepsilon \left ( t \right ) \right |}{t}dt$
3. $\int _{0}^{\infty }t\left | \varepsilon \left ( t \right ) \right |dt$
4. $\int _{0}^{\infty }t^{2}\left | \varepsilon \left ( t \right ) \right |dt$
