Question

Design a sequence detector based on Moore Machine.

(state tables, state diagrams, karnaugh maps, implement using D-FlipFlop)

sequence: 101

Answer #1

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...

We want to design a non-resetting sequence detector using a
finite state machine (FSM) with one input X and one output Y. The
FSM asserts its output Y when it recognizes the following input bit
sequence: "1101". The machine will keep checking for the proper bit
sequence and does not reset to the initial state after it has
recognized the string. [Note: As an example the input string X=
"..1101101.." will cause the output to go high twice: Y =...

Mealy and Moore state machine
For sequence “101”

Generate a MOORE design to detect sequence 110010. It should
indicate whether this sequence has been observed on our serial
input X. So, if X has had as a sequence 110010, the output Z will
be high, otherwise the output will be low. Assume that when the
machine starts up or is reset, it has not seen any bits of data to
work with and needs to observe six bits to go high.

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

Q1) Design a Moore sequence recognizer that detects the
nonoverlapping sequence “101.” Use binary encoded state labels and
design and draw the circuit schematic similar to the one shown in
Fig. 5.16. (4 pts)
Q2) Design a Mealy sequence recognizer that detects the
nonoverlapping sequence “101.” Use binary encoded state labels and
draw the circuit schematic similar to the one shown in Fig. 5.16.

5. Draw a Moore-type state diagram and design a synchronous
sequential circuit using D flip flops for a 1-input/1-output
"sequence detector" for the sequence 1001 (be sure to recognize
overlapping sequences). Use don't cares. Draw the final
circuit.

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.

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.
Example:
X = 1 0 1 0 1 1 0 1 1 0 1 1
Z = 0 0 0 0 0 0 0 0 1 0 0 1
a. Make a state diagram for the process using the Moore Machine
model
b. Make a next...
