Find the transfer function for the given signal flow graph.
1
\(\frac{G1G2 + G4 + G1G3}{1 + G1G2G4 + G2 + G3 + G4H1 + G3G4H1}\)
2
\(\frac{G1G2 + G4 + G1G3}{1 + G1G2H1 + G2 + G3 + G4H1 + G3G4H1}\)
3
\( \frac{G1G2 + G1G3}{1 + G1G2H1 + G2 + G3 + G4H1 + G3G4H1}\)
4
\(= \frac{G1G2 + G4 + G1G3}{1 + G1G2H1 + G2 + G3 + G4H1 }\)
