10 Implementation: Procedure State Table => Excitation Table Problem: To implement C, we need D(t), T(t), (S(t) R(t)), (J(t) K(t)) as functions of (x,).. From state table, we have NS: Q(t+) = g(x(t),) 2. Excitation Table of F-Fs: The setting of D(t), T(t), (S(t) R(t)), (J(t) K(t)) to drive to Q(t+). 3. Combining and 2, we have excitation table of C: D(t), T(t), (S(t) R(t)), (J(t) K(t)) = h(x,).

From & 2, we derive excitation table of the system D(t)= h D (x(t),)= e D (g(x(t),),); T(t)= h T (x(t),)= e T (g(x(t),),); (S, R) or (J, K). 4. Use K-map to derive combinational logic implementation.
