Question

1) Design a sequential circuit with two D flip-flops,
A and B, and one input, x. When x = 0, the

circuit state does not change. When x = 1, the circuit stops
through the state transitions

from 00 to 01, from 01 to 10, from 10 to 11, finally back to 00 and
the sequence repeats.

to. Find the state diagram

b. Find the table of states

c. Find the equations of state

d. Find the logic diagram

A Sequential Circuit has two D Flip-Flops, C and H, and one
input x. When x = 0, the state of the circuit remains
the same. When x =1, the circuit goes through the state transitions
from 00 to 01 to 11 to 10 back to 00, and
repeats. Design the sequential circuit.

Question 1:A) A sequential circuit has two flip-flops A and B,

circuit. b) Derive the state table and state diagram of the
circuit.

Without using Verilog, use D-type flip-flops and combinational
logic to design a synchronous Moore finite-state machine that
monitors input A and asserts a binary output B if the sequence 101
is observed. For example:
