Question

What is the steady state value of F (t), if it is known that F(s) = b/(s(s+1)(s+a)), where a>0? (a) \frac{b}{a} (b) \frac{a}{b} (c) 1 (d) Cannot be determined The question was posed to me by my school teacher while I was bunking the class.

Answer 1

The correct choice is (a) \frac{b}{a} The explanation: F (∞) = lims→0 s F(s) = lims→0 \frac{sb}{s(s+1)(s+a)} = lims→0 \frac{b}{(s+1)(s+a)} = \frac{b}{a} .
