engineering recuitment GATE IN Test Series 2023-24 Mock Test Control Systems Signal Flow Graph and Block Diagram Block Diagram Reduction Technique
A system block diagram is shown in the given figure. The overall function of the system is
\(\frac{C}{R} = \frac{{{G_1}{G_2}{G_3}}}{{1 + {G_1}{G_2}{G_3}{H_1} + {G_3}{H_2} - {G_3}{G_2}{H_3}}}\)
The value of ‘X’ would be equal
