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:C
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)
Explanation: c(t)=1-e-2t
