Answer #1

Design a Mealy finite state machine that detects the bit
sequence x=[111010].
Draw Mealy state diagram
Write state table
Implement circuit with flip flop type of your choice

Mealy state machines.
(a) Design a Mealy state machine to detect the sequence 10010.
There is a single input “x” and a single output “z”. The output is
set to 1 when the sequence is detected. Design the state machine
using gates and flip-flops in the standard way, i.e., begin with a
state transition diagram and state transition table, do plain state
assignment (e.g., for three state variables, first state is 000,
next is 001, and so on), use K-maps...

Sequence is 000,0110,111,100,101,001,
(repeat)000,…· Design a counter that counts in the sequence assigned to you.
Use D flip-flops, NAND gates, and inverters. Draw your circuit
explicitly showing all connections to gate and flip-flop inputs.Explicitly means that you should draw in all wires, don’t
just label the inputs and outputs. Show switches connected to thePreset and Clear inputs of the flip-flops. Use
one switch for all clears and a separate switch for each
preset.· Explain in detail how you can set...

Design a counter which counts in the sequence that has
been assigned to you. Use D flip flops and NAND gates. Simulate
your design using SimUaid.
Submit the state table, D flip-flop input equations,
and transition graph determined in Part 6. The D flip-flop
equations can be derived using Karnaugh maps or using LogicAid by
entering a state table with zero input variables.
Sequence: 000,100,001,110,101,111,(repeat)
000,...
Also, please answer the following questions:
How can a D flip-flop be set to...

Design the following state machine using JK flip-flops:
A state machine outputs a 1 when the sequence 010110 is
recognized and your design must accommodate overlaps. When the
sequence is detected, the sequence is detected, the sequence
detection must be signaled immediately when the last bit in the
sequence is input. Derive the K-maps for all excitation inputs.

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
---------------- time
a) Draw the state transition graph
b) Draw the encoded next state/output table
c) Determine the minimal circuit realization of the next state
logic and output
d) Draw the circuit
e) Draw a timing diagram using the input sequence above showing
the...

Design a sequencer using J-K flip-flops that will sequence

response to successive clock pulses:
0,1,3,5,7,4,0,…………..
PLEASE INCLUDE ALL OF THE FOLLOWING:
-a state diagram
-a binary state transition table
-K-maps and reduced expressions for all J-K inputs
-logic diagram

Design a synchronous machine (Transition Table, K-maps, Final
Equations, Circuit Diagram) that counts through the following
sequence in the order shown below. Note, there are no inputs or
output variables, so your Q values must reflect the Hex value
