Question

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 (HDL-see Problem 5.35): Alt + 1) = xy' + xB B(t + 1) = xA + xB' z = A (a) Draw the logic diagram of the circuit. (b) List the state table for the sequential circuit. (c) Draw the corresponding state diagram.

Answer 1

The logic diagram, state table, and state diagram for the sequential circuit can be created based on the given next-state and output equations.

Step-by-step explanation:

The logic diagram of the circuit can be drawn by representing the D flip-flops A and B as rectangles with clock inputs and D inputs, and the inputs x and y as lines entering the circuit.

The state table for the sequential circuit can be created by listing all possible combinations of the current state (A and B) and inputs (x and y), and determining the next state and output based on the given next-state and output equations.

The corresponding state diagram can be drawn by representing each state as a circle, with arrows representing the transitions between states based on the inputs.
