EE 320 – Homework #6 2. A sequential circuit has four flip-flops A,B,C,D an input x and output z. It is described by the following state equations: A(t*)=(CD’+C’D)+(CD+C’D’)x B(t*)=A C(t*)=B D(t*)=C z=AB’+CD’ Construct the state table and state diagram. 3. A sequential circuit has two flip-flops (A and B), two inputs (x and y) and an output (z). The flip- flop input functions and the circuit output function are as follow: J A =xB+y’B’ K A =xy’B’ J
