The unit impulse response of a system having transfer function K/(s+a)

1.	The unit impulse response of a system having transfer function K/(s+a) is shown below. The value of a is :(a) t1(b) t2(c) 1/t1(d) 1/t2The question was asked by my college director while I was bunking the class.The above asked question is from Time Response of First Order Systems in section Time Response Analysis, Design Specifications and Performance Indices of Control Systems
Answer» The correct option is (d) 1/t2 For EXPLANATION I WOULD SAY: G(s) = K/s+a C(s) =K/(s+a) SINCE R(s) =1 C(t) =Ke^^-at T=1/a C(t) =0.37K T= t2=1/a.
