Describe the circuit in a form of a boolean function fa b c

Question

Question 1:
(a) Given that F^D= (A+B+C+D')'E + W'XY' + (XY'+Z)ABC. What is the original function F? Do not simplify this function.

Question 2:
Given the following switching circuit with switches A, B, C, D, E, G, H, W, Y, and Z.

(a) Describe the circuit in a form of a Boolean function F(A, B, C, D, E, G, H, M, N, W, Y, Z ).

(b) Show the dual of F, F^D. Draw the switching circuit for F^D. Remember to annotate each switch with the corresponding variable.
