Hey can you answer this question for me?

For the following circuit: Analyze the following clocked synchronous sequential circuit by performing the following steps: write the equations for the flip-flop inputs and the output equation. Construct the transition and output tables. Construct the transition graph. Give a one sentence description of when the circuit produces an output of 0.

Solution

I don\'t know how to solve b & c.

a) D=Q\'+Q₂ , D=XQ\', Z=Q₁+Q\'

d) Output will be zero when Q_1,Q\' are zero.

a) D=Q\'+Q₂ , D=X, Z=Q₁+Q\'

d) Output will be zero when Q₁ ,Q\' are zero.
