Forward path = 2 (G2 & G1G2).
Loop = 1(G2).
Using Masons formula:
then TF = (G2 + G1.G2)/(1 - G2).
Loop = 1(G2).
Using Masons formula:
then TF = (G2 + G1.G2)/(1 - G2).

@Anish.
You are calculating TF between C and are. So there is only one forward path and that is G1G2.

There is only one loop.
Number of +ve loop = 1.
So, (G1G2 + G2) / (1 - G2).
Number of +ve loop = 1.
So, (G1G2 + G2) / (1 - G2).

What is the difference between transfer function and characteristic equation?

Can anyone say the correct answer please as soon as possible?

No loop is there, 3 forward path is g2 and g1g2 and 1 only.

Not correct.
The answer is [(G1 + 1) G2]/[1 - G2].
The answer is [(G1 + 1) G2]/[1 - G2].

Answer is wrong.
Answer: (G1G2/((1+G1)(1+G2))).
Answer: (G1G2/((1+G1)(1+G2))).

No. of fwd path = 3.
No. of loop = 0.
No. of loop = 0.
