(a) Construct a transition table and state graph for the given circuit. (b) Construct a timing chart for the circuit for an input sequence X = 10011. Indicate at what times Z has the correct value and specify the correct output sequence. (Assume that X changes midway between falling and rising clock edges.) Initially, Qi = Q2 = 0. %3D X Qi Qi K1 K2 J2 Clock X Clock X Q X Qi

The following state table represents a sequential circuit with two T flip-flops A and B and one input x and one output y. i- Insert the values of; TA, TB and the current state output y(t), if y(t)=[A'(t)+B`(t)]L 1. use the highlighted cells for your answers; Excitation table for T-flip flop Q(t) Q(t+1) 1 1 1 1 1 1 DEC A(t) B(t) A(t+1) B(t+1) TA TB y(t) 1 1 1 1 1 1 1 2 1 1 3 1 1 41 1 0. 1 1 1 1 1 7 1 1 1

Draw the truth tables for the following Boolean expressions. xy+yz+xz x¯y+yz¯+x¯z (x⊕y)+(y⊕z)+(x⊕z) (xy)¯⊕ z 2.Draw circuit diagrams implementing each of the above expressions. You may simplify the expressions or not, as you choose. You may use any of the six fundamental logic gates (AND, OR, NOT, NAND, NOR and XOR). I need help on question 2 containing the circuit diagrams

1- In the following sequential circuit. There are 2 D FF (A and B), 2 inputs (x and y), and 1 output z The output and next-states equations are given A(t+1) = x'y + xA B(t+1) = x'B + xA z=B b- List the state table for the sequential circuit.
