3)
A Mealy FSM to detect the sequence " 1100110" with Overlap is implemented below.
Since the length of the sequence is equal to 7 then total number of states required is also equal to 7
The states are assigned with Alphabets
SINCE THERE ARE 7 STATES NUMBER OF BITS TO REPRESENT THE STATE IS EQUAL TO 3
STATE ASSIGNMENT TABLE:
STATES | BINARY VALUE |
A | 000 |
B | 001 |
C | 010 |
D | 011 |
E | 100 |
F | 101 |
G | 110 |
STATE TRANSITION DIAGRAM :
STATE TRANSITION TABLE:
From the below state transition table we can clearly see that the output becomes 1 when there is a transition from G to C.
It implies that the required sequence has been detected and due to the overlap of the sequence the next transition state is C. but not A.
TOTAL NUMBER OF STATES =7
AND WE KNOW THAT
So, N= 3.
Hence 3 number of flipflops are required.
4)
A Moore FSM to detect the sequence " 1100110" with Overlap is implemented below.
Since the length of the sequence is equal to 7 then total number of states required is equal to 8
The states are assigned with Alphabets
SINCE THERE ARE 8 STATES NUMBER OF BITS TO REPRESENT THE STATE IS EQUAL TO 3
STATE ASSIGNMENT TABLE:
STATES | BINARY VALUE |
A | 000 |
B | 001 |
C | 010 |
D | 011 |
E | 100 |
F | 101 |
G | 110 |
H | 111 |
STATE TRANSITION DIAGRAM
STATE TRANSITION MATRIX:
From the below state transition table we can clearly see that the output becomes 1 when the Circuit enters the H state.
It implies that the required sequence has been detected and due to the overlap of the sequence the next transition state is E if input is 0 and B if input is 1 but not A.
TOTAL NUMBER OF STATES =8
AND WE KNOW THAT
So, N= 3.
Hence 3 number of flipflops are required.
Answer both parts please 3. Implement a Mealy FSM to detect the "1100110” sequence with overlap....
Design and implement a MEALY finite state machine that would detect a sequence 0110 in the input stream. Overlapping sequences are allowed. A) draw state diagram You would need no more than 4 states to implement the logic B) tabulate the state transition table C) show the implementation of the FSM using D-flip-flops
Question 6. (20 points) You are designing a sequence detector that can detect 0110', if this sequence is detected, the detector output a 1'. Please consider 'overlap', which means that even if the sequence '0110 is detected, the detector still can reuse the history data. Design a Mealy FSM. 1) .(5 points) Draw the state transition diagram. 2) (2 points) How many states are there? How many bits are needed to encode the states? 3) -(4 points) Write down the...
Design a 4-bit serial bit sequence detector. The input to your state detector is called DIN and the output is called FOUND. Your detector will assert FOUND anytime there is a 4-bit sequence of "0101". For all other input sequuences the output is not asserted. (a) (b) Provide the state diagram for this FSM. Encode your states using binary encoding. How many D-Flip-Flops does it take to implement the state memory for this FSM? (c) Provide the state transition table...
4) Design FSMs that will detect the following sequence (including overlapping sequences). When the sequence is detected, a single output "z" is set to 1. Your design should include a state transition diagram and a state transition truth table (you do NOT need to design the circuit schematic, just the transition diagram and truth table). Sequence = 110111 a. Create a Moore FSM b. Create a Mealy FSM
digital logic Design a sequential circuit for a single-input and single output Moore-type FSM that produces an output of 1 if in the input sequence it detects either 110 patterns. Overlapping sequences should be detected.(Note : use D flip-flops in your design. Repeat problem 2 for a Mealy-type FSM 2. 3. Design a sequential circuit for a single-input and single output Moore-type FSM that produces an output of 1 if in the input sequence it detects either 110 patterns. Overlapping...

Design a sequential circuit for a sequence detector that detects the sequence 10011. A continuous bit stream is fed at the input of the circuit. Every time the circuit detects the sequence 10011, an output line is made HIGH a) Sketch Mealy FSM for the sequence detector. b) Tabulate the state table c) Using K-maps, write down the simplified Boolean expressions of the flip-flops input equations using T flip-flops d) Sketch the logic circuit diagram
detect two sequence at a time by using both fsm machine (mealy and more) 011 , 110 these are two given sequence please do all step . explain every thing that why you go this state
Sequence detector: The machine has to generate z = 1 when it detects the sequence 1011. Once the sequence is detected, the circuit looks for a new sequence. The signal E is an input enable: It validates the input x, i.e., if E = 1, x is valid, otherwise x is not valid. Draw the State Diagram (any representation), State Table, and the Excitation Table of this circuit with inputs E and x and output z. Is this a Mealy or a...
