engineering recuitment RVUNL JEn (RSEB) Mock Tests 2025 Control Systems Signal Flow Graph and Block Diagram Mason's Gain Formula
With reference to the signal flow graph shown below, which one of the following will be the overall transfer function?
1
\(\frac{C}{R} = G\)
2
\(\frac{C}{R} = \frac{G}{{1 + {H_2}}}\)
3
\(\frac{C}{R} = \frac{G}{{\left( {1 + {H_1}} \right)\left( {1 + {H_2}} \right)}}\)
4
\(\frac{C}{R} = \frac{G}{{1 + {H_1} + {H_2}}}\)
5
\(\frac{C}{R} = \frac{G}{{ {H_1} + {H_2}}}\)
