A linear time-invariant system initially at rest, when subjected to a unit step input, gives a response y(t) = te-t, t > 0. The transfer function of the system is:
1
\(\frac{1}{{{{\left( {s + 1} \right)}^2}}}\)
2
\(\frac{1}{{s{{\left( {s + 1} \right)}^2}}}\)
3
\(\frac{s}{{{{\left( {s + 1} \right)}^2}}}\)
4
\(\frac{1}{{s + 1}}\)
