Find the transfer function \(\frac{{Y\left( s \right)}}{{X\left( s \right)}}\) of the system given below

\(\frac{{{G_1} + {G_2}}}{{1 - H\left( {{G_1} + {G_2}} \right)}}\)

\(\frac{{{G_1}}}{{1 - H{G_1}}} + \frac{{{G_2}}}{{1 - H{G_2}}}\)

\(\frac{{{G_1}}}{{1 + H{G_1}}} + \frac{{{G_2}}}{{1 + H{G_2}}}\)

\(\frac{{{G_1} + {G_2}}}{{1 + H\left( {{G_1} + {G_2}} \right)}}\)

Find the transfer function \(\frac{{Y\left( s \right)}}{{X\left( s \ri
