The next-state equations for a sequential circuit with two flip-flops (Q₁and Q₂), input signals R, S, T, and an output P are

D₁ = Q₁⁺ = Q₂R₁ Q₁S 

D₂ = Q₂⁺ = Q₁⁺ Q₂'T

The output equation is P = Q₂RT + Q₁ST

(a) Explain how this sequential circuit can be implemented using a single Figure 6-3 logic block. Write the equation that each function generator in the block will implement.
(b) Mark (highlight) the input signals, the state and output variables, and the activated paths on a copy of Figure 6-3.
