5.2) Construct a JK flip-flop using a D Flip-flop, a 2-to-1 line multiplexer and an inverter. 5.4) A PN flip-flop has four operations: clear to 0, no change, complement, and set to 1, when inputs P and N are 00, 01, 10, and 11, respectively. a) Tabulate the characteristic table. b) Derive the characteristic equation. c) Tabulate the excitation table. d) Show how the PN flip-flop can be converted to a D flip-flop. 5.6) A sequential circuit with two D Flip-Flops, A and B; two inputs, x and y; and one output, z, is specified by the following next-state and output equations: A(t + 1) = x'y + xA B(t+1) = x'B + xA z = B a) Draw the logic diagram of the circuit. b) List the state table for the sequential circuit. c) Draw the corresponding state diagram.
