According to Mason’s gain formula, the transfer function is given by
Where, n = no of forward paths
Mk = kth forward path gain
Δk = 1 - Sum of the loop that exists after removal of the kth forward path + sum of the gain product of two non-touching loops
Δ = 1 – (sum of the loop gains) + (sum of the gain product of two non-touching loops) – (sum of the gain product of three non-touching loops)
Calculation
While calculating output C1 due to R1 and R2 , keep C2 = 0
The forward path from R1 to C1 is:
The forward path from R2 to C1 is:
Self-loop gain:
Hence, the correct answer is option 1.
