Q. Use mason’s gain formula to find the transfer function of the given signal flow graph:

(A) abd/1-(ac)
(B) abdeg/1-(bc+ef)+bcef
(C) abd/1-(bc+ef)+bcef
(D) adcdef/1-(bc+ef)+bcef
Correct : Option (B)

Explanation: 
 using mason’s gain formula transfer function from signal flow graph can be calculated which relates the forward path gain to the various paths and loops.
