Using behavioral VHDL, design a Moore-type
finite state machine that detects input test vector that contains
the sequence of ‘100’. If the sequence ‘100’ is detected, the
output Z should go high. The input is to be named W, the output is
to be named Z, a Clock input is to be used and an active low reset
signal (Resetn) should asynchronously reset the machine.
a) Draw the Moore-type model state
diagram for the FSM.
b) Write the VHDL code...
Write a VHDL code to implement a Finite State Machine that with
an 8 bit sequence input (can be any sequence, but lets say it is
11001000), determine how many states there are as well; so if the
input sequence is correct it will show the number 1 in a 7 segment
display, otherwise it will be 0 in the same 7 segment display. If
the input sequence is incorrect, start from the beginning.
1. write a truth table using this symbol: -->

3. write the compliment, or NOT using '
As an example:
The truth table for AND is written this way:
A B --> A AND B
0 0 --> 0
0 1 --> 0
1 0 --> 0

What is a finite-state machine ?
What is a pushdown automaton ?
What is a Turing machine?
What is a Turing complete language?
Compare the finite-state machine , pushdown automaton ,
and Turing machine.?
Design a Moore state machine that has an input w and an output z
that should output a ‘1’ when the previous 4 values of w were 1001
or 1111. Overlapping patterns are allowed. Show the state diagram
and state table. Use a simple binary counting order for the state
assignment. Derive all of the next-state and output equations. You
do not need to draw the resulting circuit, instead write a Verilog
module for it.
Now considering an SR NAND latch as a finite state machine,
please draw the corresponding state transition diagram. You don’t
have to show the outputs in the diagram.
What would be the state diagram of the following:
The traffic light cycle will have 5 states:
State 1: Transition into Major (NS) traffic, All lights red
State 2: Left turn signals Major are on
State 3: Major roadway straight green lights on
State 4: Transition into Country (EW) traffic, All lights
red
State 5: Country roadway straight green lights on
* In-state only light are listed are not red others are red.
*Major straight-lane is green for 10 sec....
Write a program in C++ that will output the truth table for a
simple wff. There will only be Ps and Qs, so you can hard code the
P truth table and the Q truth table into arrays. The user will use
A for ^ , O for V, N for ' , & I for -> .
Hint: Read the first character, load the appropriate truth table
into the first working array. Read the next character. If it is...
