${\displaystyle h\left(t\right)=\frac{1}{K_{\text{ε}}}.\Delta v_{\text{ε}}\left(t\right)}$

Note 1 to entry: The unit-step response may be calculated from the unit-impulse response by

${\displaystyle h\left(t\right)={\displaystyle \underset{-\infty }{\overset{t}{\int }}g\left(\tau \right)}\text{d}\tau }$.

Note 2 to entry: The unit-step response of a system mathematically may be considered to result from application of a unit step to an input variable.
