In this practice exercise, you have the opportunity to go through the sequential analysis example done in lecture. From a circuit, you derive the next-state table. Although it is not done in this on-line exercise, be sure you can do one more step: draw the state diagram. Shown below is a sequential circuit with one input x and one output z and consisting of two D flip-flops. (a) Directly from the circuit, please give SOP expressions for z, D A , and D B . z(A,B,x) = xBA' Enter a SOP Boolean expression D A (A,B,x) = x'A+xB' Enter a SOP Boolean expression D B (A,B,x) = x'B+xA Enter a SOP Boolean expression
