  1. Construct a finite-state machine, using combinational logic, which reads in one bit at a time. When a nibble (4 bits) are all zeros the output is set to one else the output is zero. The machine continues to read in bits and the output remains a one if zeros are read in. If it reads a one the output is a zero.
    1. What are the machine states?
    2. What are the inputs?
    3. What are the outputs?
    4. Draw state table.
    5. Draw the state diagram.
    6. Define the circuit for the next state and the output with the Boolean equations.
    7. Explain if you built a Mealy or Moore machine.

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.

Code the FSM in C++, and show that the program works. Construct a Finite State Machine that models an old-fashioned soda machine that accepts nickels, dimes, and quarters. The soda machine accepts change until 35 cents have been put in. It gives change back for any amount greater than 35 cents. Then the customer can push buttons to receive either a cola, a root beer, or a ginger ale.

1. Design a sequence detector, a Mealy finite state machine to detect the serial bit sequence 1101, where the most significant bit (MSB) comes first and the least significant bit comes last. A) Draw the state diagram B) Draw the state table C) The circuit is to be implemented using JK flip-flops and combinational logic circuit. Derive the Boolean expression necessary for this implementation. D) Sketch the circuit diagram for your design. This should show all the flipflops, logic gates...

Problem Statement: Design a combinational logic circuit that meets the following specifications: • Input: 3-bit binary integer (A), 2-bit binary integer (B). • Output: 5-bit binary integer (X) = (AxB). For example, A=6, B=2, X=6x2=12. Notation: • A=(A2,A1,A0) • B=(B1,B0) • X=(X4,X3,X2,X1,X0) Required Output: Show the truth table and a minimal logic expression for each of the outputs. Also, draw a logic diagram using discrete gates. Extra Credit: Redesign by using multiplexers and minimal discrete logic as appropriate. 1 |...

Consider a finite state machine with a control input called mode. When mode = 0, the machine operates as a mod-3 down counter, where the outputs are the count values. When mode = 1, the machine's output progresses through the last 4 digits of your WCU ID (1133) number (1 digit per clock cycle). Complete each of the steps which follow. (a) Draw the state diagram for this machine. (b) Write RTL Verilog code which implements this design. Submit your...

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...
