Question

A linear system at rest is subject to an input signal r(t)=1-e-t. The response of the system for t>0 is given by c(t)=1-e-2t. The transfer function of the system is:
a) (s+2)/(s+1)
b) (s+1)/(s+2)
c) 2(s+1)/(s+2)
d) (s+1)/2(s+2)​

Answer 1

Explanation:

c(t)=1-e-2t

R(s)=1/s-1/s+1

C(s)=1/s-1/s+2

Tf=2(s+1)/(s+2).
