6) Use Mason’s rule to figure out the equivalent input/output transfer functions

Don't use ai to answer I will report your answer Solve it Asap with explanation and calculation

(a) For each of these blocks now write down the transfer that will describe the input- output characteristics of that block. Va(s) I(s) T(s) e(s) Vo(s)
