A
$${{{G_1}} \over {1 + {G_2}\left( {1 + {G_1}} \right)}}$$

GATE EE 2014 Set 3

MCQ (Single Correct Answer)
The signal flow graph of a system is shown below. $$U(S)$$ is the input and $$C(S)$$ is the output.

Assuming $${h_1} = {b_1}$$ and $${h_0} = {b_0} - {b_1}{a_1},$$ the input-output transfer function, $$G\left( S \right) = {{C\left( S \right)} \over {U\left( S \right)}}$$ of the system is given by

A
$$G\left( S \right) = {{{b_0}s + {b_1}} \over {{s^2} + {a_0}s + {a_1}}}$$
B
$$G\left( S \right) = {{{a_1}s + {a_0}} \over {{s^2} + {b_1} + {b_0}}}$$
C
$$G\left( S \right) = {{{b_1}s + {b_0}} \over {{s^2} + {a_1}s + {a_0}}}$$
D
$$G\left( S \right) = {{{a_0}s + {a_1}} \over {{s^2} + {b_0}s + {b_1}}}$$
