Consider the following logic circuit with one J-K flip-flop and one D flip-flop. x is the input variable and z is the output variable. Clock is the clock input. Clock 91 K 9₁ D 92 92 a) Express the boolean expressions for the inputs of the J-K flip-flop and the D flip- flop, namely J, K, and D, in terms of the input variable x, and their current state variables, q1, 91, 92 and q2'. b) Express the boolean expression for the output variable z, in terms of the input variable X, and their current state variables, q1, 91, 92 and q2'. c) Write down the state transition table, in terms of present states, input, next states, output and the flip-flop inputs. (d) Construct the state diagram, labelled with states in circles, and input/output on each arrow.
