The transfer function C/R of the system shown in the figure is
1
\(\frac{{{G_1}{G_2}}}{{1 + {G_1}{H_1} + {G_2}{G_2}}}\)
2
\(\frac{{{G_1}{H_1}{G_2}{H_2}}}{{\left( {1 + {G_1}{H_1}} \right)\left( {1 + {G_2}{H_2}} \right)}}\)
3
\(\frac{{{G_1}{G_2}}}{{1 - {G_1} - {G_2} + {G_1}{G_2}{H_1}{H_2}}}\)
4
\(\frac{{{G_1}{G_2}}}{{1 + {G_1}{H_1} + {G_2}{H_2} + {G_1}{G_2}{H_1}{H_2}}}\)
