Use elimination to flatten each of the function sets given into a two-level sumof-products form.

(a) \(F(A, B, G, H)=A B \bar{G}+\bar{B} G+\bar{A} \bar{H}, G(C, D)=C \bar{D}+\bar{C} D\), \(H(B, C, D)=B+C D\)

(b) \(T(U, V, Y, Z)=Y Z U+\bar{Y} \bar{Z} V, U(W, X)=W+\bar{X}\), \(V(W, X, Y)=\bar{W} Y+X\)
