Question

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 design. use DFF and draw the circuit

Answer #1

Design a sequential circuit which has an input line x
and an output line y.
The circuit receives input from a single source in the
form of a string of ‘1’ s and 0’s .
The output goes to ‘1’ once three consecutive ‘1’s are
seen on the input, and remains 1 as long as it continues to receive
‘1’ on the input line. If it receives a ‘0’ the output goes to ‘0’
again..

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.

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.

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

Using Moore machine approach design a sequence detector with one
input and one output. When input
sequence 010 occurs the output becomes 1 and remains 1 until the
sequence 010 occurs again in which case the
output returns to 0. The output remains 0 until, 010 occurs the
third time, and so on. Your design should be
able to handle overlapping sequences, i.e., input sequence
11001010100 should produce the output 00000110011.
Draw the state diagram and implement your detector using...

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...

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.

Create a FSM that detects the input bit pattern ‘01’. The output
will be ‘0’ until the exact pattern ‘01’ is received. At the point
of receiving ‘01’, the FSM will output 1, and then go back to
output ‘0’ until the next ‘01’ is received.
1) Draw the Moore FSM diagram for the above
2) Write the FSM tables:
a. State Assignment (Gray Encoding)
b. State Output
c. State Transition Tables
3) Simplify the Output logic (use K-Map if...

3. Parity generator [20]
Submission file for this part: 3.circ
Main circuit name: paritygen
Input pin(s): inputw [1], sysclock [1]
Output pin(s): outputq [1]
Derive a minimal state table for a Moore model FSM that acts as
a three-bit parity generator. For every three bits that are
observed on inputw during three consecutive clock cycles,
the FSM generates the parity bit outputq = 1 if the number
of 1s received in the sequence so far is odd. Thus, this is...
