Question

Create a sequential circuit Moore machine with 2 D flip flops and 3 states (s0, s1, s2), with any gates needed.

The machine must be able to recognize any amount of xy=10 followed by xy=01. 2 inputs X and Y, and one output Z.

A sample input sequence and output response is given below.

x = 0 1 1 0 0 0 1 0 1 1 0 0 1

y = 0 0 0 1 1 0 0 1 0 0 1 1 0

z = 0 0 0 1 0 0 0 1 0 0 1 0 0

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.

Design a Sequence Recognizer that will recognize the sequence
101101 by designing a finite state machine (FSM). The input will be
(X) and when the pattern is seen the output (Z) will be 1.

A sequential circuit has three T Flip Flops: A, B and C and one
input x and one output y. The circuit is described by the following
state equations:
TA = x’+ B’ TB = x(A+C') TC = x’
y = (B'+ C)x
Draw the circuit diagram.
Derive the state transition table
Derive the state diagram.

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:
A=010101101
B=000101001

Question 1
A sequential pattern detection circuit (state machine) has input
A and output Y, which becomes 1 whenever input pattern of 1 1 0 is
detected on the input
Draw the state transition diagram for this circuit. Simply use
state names S0, S1, S2… without any state encoding
Using one-hot-encoding draw the state transition table. Clearly
show input(s). present state and next state variables and
output(s).
Write next state and output equations.

Design a 6-bit, shift-right register with D flip flops, and use
it to implement a circuit that detects the sequence “010010” (the
rightmost bit is the first arriving). Information shifts one
position right when a positiv edge of clk occurs The circuit has
the following inputs and outputs (use exactly these names for
inputs and outputs. Respect upper and lower case):
clk: Input. Clock signal.
RST: Reset signal. When RST = 1 flip flops are reset to 0.
IN: Data...

design a moore sequential circuit with one input x and one
output z such that z=1 if the total number of 1's received is odd
and the total number of 0's received is an even number greater than
0. (6 states)
sample input x: 010011101010010101101
z: 001000001000001000001
derive the starte diagram. use one-hot state assignment for the
