The block diagram of a feedback control system is shown in the figure. The overall closed-loop gain of $G$ of the system is 

  1. $G = \large\frac{G_1G_2}{1+G_1H_1} \\$
  2. $G = \large\frac{G_1G_2}{1+G_1G_2+G_1H_1} \\$
  3. $G = \large\frac{G_1G_2}{1+G_1G_2H_1} \\$
  4. $G = \large\frac{G_1G_2}{1+G_1G_2+G_1G_2H_1}$
